Current multi-byte related codes have a bug with SQL_ASCII
support. Included patches will solve it and should be applied to
both trees. Also, it fix the problem with \c command of psql when
switching different encoding databases.
Add support for the CASE statement in the rewrite handling.
Allows (at least some) rules and views.
Still some trouble (crashes) with target CASE columns spanning tables,
but lots now works.
Fix up error messages when looking up functions and operators to not
make the sometimes misleading claim that more than one candidate was
identified. Now say "Unable to identify...".
Clean up error messages associated with rules and views.
Fix parser error message when an operator is not found
to not explicitly claim that there is more than one.
Add routines and synonyms to help with single-byte char type handling.
Fix one usage of substr() which mapped to the "Oracle compatibility" funcs
rather than the more recent (and closer to SQL92) function in varlena.c.
Add more DESC() entries for conversion functions.
Adjust handling of data type names to suppress double quotes
unless necessary.
Label internal bpchar types as "character" and varchar types as
"character varying" to be less Postgres-specific. These types map to
the SQL92 definitions anyway.
Redefine g_force_quotes to be the local variable force_quotes.
Pass this as an argument to fmtId().
These should help with handling the single-byte internal "char" type.
Switch around conditional code so that HAVE_TM_ZONE takes precedence
over HAVE_INT_TIMEZONE. This may help out linux/glibc2 and Dec Alpha.
Included #error precompiler macros to catch cases where neither is defined
but USE_POSIX_TIME is (shouldn't happen). Hopefully this isn't just
a gcc-ism.

Partial fix for vendor-cc-versus-gcc incompatibility on HPUX:
prefer aCC as c++ compiler if hpux_cc is selected as template.
Doesn't solve the problem if you have g++ and not aCC, however...

Use standard AC_PROG_INSTALL macro to search for install program,
instead of our own halfway-there code. Add AC_STRUCT_TIMEZONE call
to check whether tm_zone exists in struct tm. Revise reading of template
file so that templates can define any variables they feel like (and,
indeed, can execute arbitrary shell code) rather than being constrained
to a fixed set of variable names.

While investigating a user's complaint, I have found some memory
destructions in 6.4 source using purify.
(1) parser/gram.y:fmtId()
It writes n+3 bytes into n+1 byte-long memory area if mixed case or
non-ascii identifiers given.
(2) catalog/index.c:
ATTRIBUTE_TUPLE_SIZE bytes are allocated but
sizeof(FormData_pg_attribute) bytes are written. Note that
ATTRIBUTE_TUPLE_SIZE is smaller than
sizeof(FormData_pg_attribute). (for example, on solaris 2.6,

This patch fixes the undefined (according to C) and erroneous (under
Digital Uni x with both DEC cc and gcc) behaviour of modifying an
lvalue on the left side an d then using it on the right side of an
assignment. Since this code modifies the
dbname parameter, it was changing, for example, "dbname=template1"
into "dbname =emplate1".
Define routines and catalog entries for string min()/max() functions.
Extend new type coersion techniques to aggregates.
Clean up a few elog() messages.

Portability fixes found needed for SunOS 4.1.x:
SunOS has tas(), but not memmove or strerror, and its sprintf() doesn't

Use autoconf to determine whether system has POSIX signals,

configure unsets USE_TK if X libraries not found.

pq_getstr didn't handle buffer overrun correctly; it would
fail to consume the rest of the input string, and worse it would write
one more byte than it should into the buffer, probably resulting in coredump.
Fortunately there's a correct implementation next door in pqcomprim.c.

modify configure so that template/.similar entries can be
selected when they match a prefix of the value. The previous method,
which stripped all version data from and then tried to match that
against .similar entries, was entirely useless when .similar contained

Fix a potential infinite loop in appendStringInfo: would lock
up if first string to be appended to an empty StringInfo was longer
than the initial space allocation.
Also speed it up slightly.
Add "-N" flag to force double quotes around identifiers.
This is the default, but the new flag will allow overriding an alias,
for example. So psql -n -N will put in the double quotes,
and psql -n can be an alias for psql.
Also, add a few braces around a nested single-line conditional construct
to suppress compiler warnings about "an ambiguous else".
Cleanup for v6.4 release.
Make new file current.sgml to hold release info for the current release.
Should be moved to release.sgml before filling with next release info.

Minor FreeBSD fixes put in place
From: SHIOZAKI Takehiko <takehi-s@ascii.co.jp>
I tried snapshot(Oct30) and made some patches.
# I think that it is confused to manage both Makefile.shlib and
# makefiles/Makefile.*, don't you?
* configure
Now FreeBSD 2.X is not supported..., so I added its entry.
If ELF_SYSTEM is set, gmake treat it defined even though
it is "false". So nothing should be set to use "ifdef".
BSD_SHLIB etc. may have same problems.
* Makefile.shlib
As you said, FreeBSD entry is much like BSD's.
I only added ELF_SYSTEM code.
* makefiles/Makefile.freebsd
Ifdef/else/endif can not be indented with TABs.
Minor editing and markup changes as a result of preparing the Postscript
documentation for v6.4.
Bigger updates to the installation instructions (install and config).
Remove obsolete file listing support resources which has not been updated
in a year an a half. Much of the info was wrong and is covered more
correctly elsewhere.
Minor fix for Jan to remove claim in SPI and trigger chapters that
Postgres is missing a procedural language. He correctly points out
that we now have two (thanks to him, but he modestly didn't mention
that).
