Modify locale code to defend against possibility that it was compiled
with an -fsigned-char/-funsigned-char setting opposite to that of libc,
thus breaking the convention that 'undefined' values returned by
localeconv() are represented by CHAR_MAX. It is sheer stupidity that
gcc even has such a switch --- it's just as bad as the structure-packing
control switches offered by the more brain-dead PC compilers --- and
as for the behavior of Linux distribution vendors who set RPM_OPT_FLAGS
differently from the way they built libc, well, words fail me...

Change SearchSysCache coding conventions so that a reference count is
maintained for each cache entry. A cache entry will not be freed until
the matching ReleaseSysCache call has been executed. This eliminates
worries about cache entries getting dropped while still in use. See
my posting to pg-hackers of even date for more info.

Extend CREATE DATABASE to allow selection of a template database to be
cloned, rather than always cloning template1. Modify initdb to generate
two identical databases rather than one, template0 and template1.
Connections to template0 are disallowed, so that it will always remain
in its virgin as-initdb'd state. pg_dumpall now dumps databases with
restore commands that say CREATE DATABASE foo WITH TEMPLATE = template0.
This allows proper behavior when there is user-added data in template1.

Ok, You guys are probably tired of me, BUT, here is another one, that

UUNET is looking into offering PostgreSQL as a part of a managed web
hosting product, on both shared and dedicated machines. We currently
offer Oracle and MySQL, and it would be a nice middle-ground.
However, as shipped, PostgreSQL lacks the following features we need
that MySQL has:
1. The ability to listen only on a particular IP address. Each
hosting customer has their own IP address, on which all of their
servers (http, ftp, real media, etc.) run.
2. The ability to place the Unix-domain socket in a mode 700 directory.
This allows us to automatically create an empty database, with an
empty DBA password, for new or upgrading customers without having
to interactively set a DBA password and communicate it to (or from)
the customer. This in turn cuts down our install and upgrade times.
3. The ability to connect to the Unix-domain socket from within a
change-rooted environment. We run CGI programs chrooted to the
user's home directory, which is another reason why we need to be
able to specify where the Unix-domain socket is, instead of /tmp.
4. The ability to, if run as root, open a pid file in /var/run as
root, and then setuid to the desired user. (mysqld -u can almost
do this; I had to patch it, too).
The patch below fixes problem 1-3. I plan to address #4, also, but
haven't done so yet. These diffs are big enough that they should give
the PG development team something to think about in the meantime :-)
Also, I'm about to leave for 2 weeks' vacation, so I thought I'd get
out what I have, which works (for the problems it tackles), now.
With these changes, we can set up and run PostgreSQL with scripts the
same way we can with apache or proftpd or mysql.
In summary, this patch makes the following enhancements:
1. Adds an environment variable PGUNIXSOCKET, analogous to MYSQL_UNIX_PORT,
and command line options -k --unix-socket to the relevant programs.
2. Adds a -h option to postmaster to set the hostname or IP address to
listen on instead of the default INADDR_ANY.
3. Extends some library interfaces to support the above.
4. Fixes a few memory leaks in PQconnectdb().
The default behavior is unchanged from stock 7.0.2; if you don't use
any of these new features, they don't change the operation.

Keep track of the last active slot in the shared ProcState array, so
that search loops only have to scan that far and not through all maxBackends
entries. This eliminates a performance penalty for setting maxBackends
much higher than the average number of active backends. Also, eliminate
no-longer-used 'backend tag' concept. Remove setting of environment
variables at backend start (except for CYR_RECODE), since none of them
are being examined by the backend any longer.

Restructure handling of inheritance queries so that they work with outer
joins, and clean things up a good deal at the same time. Append plan node
no longer hacks on rangetable at runtime --- instead, all child tables are
given their own RT entries during planning. Concept of multiple target
tables pushed up into execMain, replacing bug-prone implementation within
nodeAppend. Planner now supports generating Append plans for inheritance
sets either at the top of the plan (the old way) or at the bottom. Expanding
at the bottom is appropriate for tables used as sources, since they may
appear inside an outer join; but we must still expand at the top when the
target of an UPDATE or DELETE is an inheritance set, because we actually need
a different targetlist and junkfilter for each target table in that case.
Fortunately a target table can't be inside an outer join... Bizarre mutual
recursion between union_planner and prepunion.c is gone --- in fact,
union_planner doesn't really have much to do with union queries anymore,
so I renamed it grouping_planner.
Allow interpretation of INTERVALs with more timezone-like syntax.
Define conversions to and from text for date, time, and timetz.
