+ <title>Overview</title>
+
+ <para>
+ Major changes in this release:
+
+ <variablelist>
+ <varlistentry>
+ <term>
+ <literal>IN</literal> / <literal>NOT IN</literal> subqueries are
+ now much more efficient
+ </term>
+
+ <listitem>
+ <para>
+ In previous releases, <literal>IN</literal>/<literal>NOT
+ IN</literal> subqueries were joined to the upper query by
+ sequentially scanning the subquery looking for a match. The
+ 7.4 code uses the same sophisticated techniques used by
+ ordinary joins and so is much faster. An
+ <literal>IN</literal> will now usually be as fast as or faster
+ than an equivalent <literal>EXISTS</literal> subquery; this
+ reverses the conventional wisdom that applied to previous
+ releases.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Improved <literal>GROUP BY</literal> processing by using hash buckets
+ </term>
+
+ <listitem>
+ <para>
+ In previous releases, rows to be grouped had to be sorted
+ first. The 7.4 code can do <literal>GROUP BY</literal>
+ without sorting, by accumulating results into a hash table
+ with one entry per group. It will still use the sort
+ technique, however, if the hash table is estimated to be too
+ large to fit in <varname>sort_mem</>.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ New multikey hash join capability
+ </term>
+
+ <listitem>
+ <para>
+ In previous releases, hash joins could only occur on single
+ keys. This release allows multicolumn hash joins.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Queries using the explicit <literal>JOIN</literal> syntax are
+ now better optimized
+ </term>
+
+ <listitem>
+ <para>
+ Prior releases evaluated queries using the explicit
+ <literal>JOIN</literal> syntax only in the order implied by
+ the syntax. 7.4 allows full optimization of these queries,
+ meaning the optimizer considers all possible join orderings
+ and chooses the most efficient. Outer joins, however, must
+ still follow the declared ordering.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Faster and more powerful regular expression code
+ </term>
+
+ <listitem>
+ <para>
+ The entire regular expression module has been replaced with a
+ new version by Henry Spencer, originally written for Tcl. The
+ code greatly improves performance and supports several flavors
+ of regular expressions.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Function-inlining for simple SQL functions
+ </term>
+
+ <listitem>
+ <para>
+ Simple SQL functions can now be inlined by including their SQL
+ in the main query. This improves performance by eliminating
+ per-call overhead. That means simple SQL functions now
+ behave like macros.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Full support for IPv6 connections and IPv6 address data types
+ </term>
+
+ <listitem>
+ <para>
+ Previous releases allowed only IPv4 connections, and the IP
+ data types only supported IPv4 addresses. This release adds
+ full IPv6 support in both of these areas.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Major improvements in SSL performance and reliability
+ </term>
+
+ <listitem>
+ <para>
+ Several people very familiar with the SSL API have overhauled
+ our SSL code to improve SSL key negotiation and error
+ recovery.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Make free space map efficiently reuse empty index pages,
+ and other free space management improvements
+ </term>
+
+ <listitem>
+ <para>
+ In previous releases, B-tree index pages that were left empty
+ because of deleted rows could only be reused by rows with
+ index values similar to the rows originally indexed on that
+ page. In 7.4, <command>VACUUM</command> records empty index
+ pages and allows them to be reused for any future index rows.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ SQL-standard information schema
+ </term>
+
+ <listitem>
+ <para>
+ The information schema provides a standardized and stable way
+ to access information about the schema objects defined in a
+ database.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Cursors conform more closely to the SQL standard
+ </term>
+
+ <listitem>
+ <para>
+ The commands <command>FETCH</command> and
+ <command>MOVE</command> have been overhauled to conform more
+ closely to the SQL standard.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Cursors can exist outside transactions
+ </term>
+
+ <listitem>
+ <para>
+ These cursors are also called holdable cursors.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ New client-to-server protocol
+ </term>
+
+ <listitem>
+ <para>
+ The new protocol adds error codes, more status information,
+ faster startup, better support for binary data transmission,
+ parameter values separated from SQL commands, prepared
+ statements available at the protocol level, and cleaner
+ recovery from <command>COPY</command> failures. The older
+ protocol is still supported by both server and clients.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ <application>libpq</application> and
+ <application>ECPG</application> applications are now fully
+ thread-safe
+ </term>
+
+ <listitem>
+ <para>
+ While previous <application>libpq</application> releases
+ already supported threads, this release improves thread safety
+ by fixing some non-thread-safe code that was used during
+ database connection startup. The <command>configure</command>
+ option <option>--enable-thread-safety</option> must be used to
+ enable this feature.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ New version of full-text indexing
+ </term>
+
+ <listitem>
+ <para>
+ A new full-text indexing suite is available in
+ <filename>contrib/tsearch2</filename>.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ New autovacuum tool
+ </term>
+
+ <listitem>
+ <para>
+ The new autovacuum tool in
+ <filename>contrib/autovacuum</filename> monitors the database
+ statistics tables for
+ <command>INSERT</command>/<command>UPDATE</command>/<command>DELETE</command>
+ activity and automatically vacuums tables when needed.
+ </para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term>
+ Array handling has been improved and moved into the server core
+ </term>
+
+ <listitem>
+ <para>
+ Many array limitations have been removed, and arrays behave
+ more like fully-supported data types.
+ </para>

+ <sect2>
+ <title>Migration to version 7.4</title>
+
+ <para>
+ A dump/restore using <application>pg_dump</application> is
+ required for those wishing to migrate data from any previous
+ release.
+ </para>
+
+ <para>
+ Observe the following incompatibilities:
+
+ <itemizedlist>
+ <listitem>
+ <para>
+ The server-side autocommit setting was removed and
+ reimplemented in client applications and languages.
+ Server-side autocommit was causing too many problems with
+ languages and applications that wanted to control their own
+ autocommit behavior, so autocommit was removed from the server
+ and added to individual client APIs as appropriate.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Error message wording has changed substantially in this
+ release. Significant effort was invested to make the messages
+ more consistent and user-oriented. If your applications try to
+ detect different error conditions by parsing the error message,
+ you are strongly encouraged to use the new error code facility instead.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Inner joins using the explicit <literal>JOIN</literal> syntax
+ may behave differently because they are now better
+ optimized.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ A number of server configuration parameters have been renamed
+ for clarity, primarily those related to
+ logging.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <literal>FETCH 0</literal> or <literal>MOVE 0</literal> now
+ does nothing. In prior releases, <literal>FETCH 0</literal>
+ would fetch all remaining rows, and <literal>MOVE 0</literal>
+ would move to the end of the cursor.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <command>FETCH</command> and <command>MOVE</command> now return
+ the actual number of rows fetched/moved, or zero if at the
+ beginning/end of the cursor. Prior releases would return the
+ row count passed to the command, not the number of rows
+ actually fetched or moved.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <command>COPY</command> now can process files that use
+ carriage-return or carriage-return/line-feed end-of-line
+ sequences. Literal carriage-returns and line-feeds are no
+ longer accepted in data values; use <literal>\r</literal> and
+ <literal>\n</literal> instead.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Trailing spaces are now trimmed when converting from type
+ <type>char(<replaceable>n</>)</type> to
+ <type>varchar(<replaceable>n</>)</type> or <type>text</type>.
+ This is what most people always expected to happen anyway.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ The data type <type>float(<replaceable>p</>)</type> now
+ measures <replaceable>p</> in binary digits, not decimal
+ digits. The new behavior follows the SQL standard.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Ambiguous date values now must match the ordering specified by
+ the <varname>datestyle</varname> setting. In prior releases, a
+ date specification of <literal>10/20/03</> was interpreted as a
+ date in October even if <varname>datestyle</> specified that
+ the day should be first. 7.4 will throw an error if a date
+ specification is invalid for the current setting of
+ <varname>datestyle</>.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ The functions <function>oidrand</function>,
+ <function>oidsrand</function>, and
+ <function>userfntest</function> have been removed. These
+ functions were determined to be no longer useful.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ String literals specifying time-varying date/time values, such
+ as <literal>'now'</literal> or <literal>'today'</literal> will
+ no longer work as expected in column default expressions; they
+ now cause the time of the table creation to be the default, not
+ the time of the insertion. Functions such as
+ <function>now()</>, <function>current_timestamp</>, or
+ <function>current_date</function> should be used instead.
+ </para>
+
+ <para>
+ In previous releases, there was special code so that strings
+ such as <literal>'now'</literal> were interpreted at
+ <command>INSERT</> time and not at table creation time, but
+ this work around didn't cover all cases. Release 7.4 now
+ requires that defaults be defined properly using functions such
+ as <function>now()</> or <function>current_timestamp</>. These
+ will work in all situations.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ The dollar sign (<literal>$</>) is no longer allowed in
+ operator names. It can instead be a non-first character in
+ identifiers. This was done to improve compatibility with other
+ database systems, and to avoid syntax problems when parameter
+ placeholders (<literal>$<replaceable>n</></>) are written
+ adjacent to operators.

- This removes our old
- table-level locking, and replaces it with a locking system that is
- superior to most commercial database systems. In a traditional system,
- each row that is modified is locked until committed, preventing reads by
- other users. MVCC uses the natural multiversion nature of PostgreSQL
- to allow readers to continue reading consistent data during writer
- activity. Writers continue to use the compact pg_log transaction
- system. This is all performed without having to allocate a lock for
- every row like traditional database systems. So, basically, we no
- longer are restricted by simple table-level locking;
- we have something better than row-level locking.
