Scrapped pg_version and changed initdb accordingly. Integrated
src/utils/version.c into src/backend/utils/init/miscinit.c. Changed all
callers.

Set version number to `7.1devel'. (Non-numeric version suffixes now allowed.)

just pass in CPP and AWK via the environment from the Makefile.

 Now the to_timestamp() support WW,W,J,SSSS,DDD conversion from strings and
the am/pm bug is fixed, the to_char() use week-of-year (WW) full compatible
with Oracle.

 This patch update relevant regress-tests and docs too.

entry that has rules.  This allows us to release the rule parsetrees
on relcache flush without needing a working freeObject() routine.
Formerly, the rule trees were leaked permanently at relcache flush.
Also, clean up handling of rule creation and deletion --- there was
not sufficient locking of the relation being modified, and there was
no reliable notification of other backends that a relcache reload
was needed.  Also, clean up relcache.c code so that scans of system
tables needed to load a relcache entry are done in the caller's
memory context, not in CacheMemoryContext.  This prevents any
un-pfreed memory from those scans from becoming a permanent memory
leak.

does not have it.

for details).  It doesn't really do that much yet, since there are no
short-term memory contexts in the executor, but the infrastructure is
in place and long-term contexts are handled reasonably.  A few long-
standing bugs have been fixed, such as 'VACUUM; anything' in a single
query string crashing.  Also, out-of-memory is now considered a
recoverable ERROR, not FATAL.
Eliminate a large amount of crufty, now-dead code in and around
memory management.
Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and
backend startup.

Japan. Can someone comment on this? According to him, with the patch
now only the geometry test fails.

option settings. Sort out SIGHUP vs BACKEND -- there is no total ordering
here, so make explicit checks. Add comments explaining all of this.
Removed permissions check on SHOW command.

Add examine_subclass to the game, rename to SQL_inheritance to fit the
official data model better. Adjust documentation.

Standalone backend needs to reset all options before it starts. To
facilitate that, have IsUnderPostmaster be set by the postmaster itself,
don't wait for the magic -p switch.

Also make sure that all environment variables and argv's survive
init_ps_display(). Use strdup where necessary.

Have initdb make configuration files (postgresql.conf, pg_hba.conf) mode

the underlying table at all, just change the mapping entry ... but
that logic was missing.

to apply the tempname->realname mapping to type name lookup as well
as relation name lookup, else the type tuple will not be found when
wanted.  This fixes bugs like this one:
create temp table foo (f1 int);
select foo.f2 from foo;
ERROR:  Unable to locate type name 'foo' in catalog

are opened in a consistent order by different backends (I ordered them
by index OID because that's easy, but any other consistent order would
do as well).  This avoids potential deadlock for index types that we
acquire exclusive locks on ... ie, rtree.

entries now for int8 and network hash indexes.  int24_ops and int42_ops
are gone.  pg_opclass no longer contains multiple entries claiming to be
the default opclass for the same datatype.  opr_sanity regress test
extended to catch errors like these in the future.

materialized tupleset is small enough) instead of a temporary relation.
This was something I was thinking of doing anyway for performance, and Jan
says he needs it for TOAST because he doesn't want to cope with toasting
noname relations.  With this change, the 'noname table' support in heap.c
is dead code, and I have accordingly removed it.  Also clean up 'noname'
plan handling in planner --- nonames are either sort or materialize plans,
and it seems less confusing to handle them separately under those names.

discussion of 5/19/00).  pg_index is now searched for indexes of a
relation using an indexscan.  Moreover, this is done once and cached
in the relcache entry for the relation, in the form of a list of OIDs
for the indexes.  This list is used by the parser and executor to drive
lookups in the pg_index syscache when they want to know the properties
of the indexes.  Net result: index information will be fully cached
for repetitive operations such as inserts.

pointers, namely the catcache tuple fetch routines.  Also get rid of
the unused and possibly confusing 'size' field in struct cachedesc.
Since it doesn't allow for variable-length fields, anyone who
actually trusted it would likely be making a mistake...

Add options to configure to automatically build for Kerberos
support; no more editing of make files.

we'll get there one day.

Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.

Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.

--- ie, they're only called for side-effects.  Add a PG_RETURN_VOID()
macro and use it where appropriate.  This probably doesn't change the
machine code by a single bit ... it's just for documentation.

to_char.  I don't know about the rest of the world, but the "standard" in
Australia is the following:

        1st, 2nd, 3rd, 4th - 9th
        10th - 19th
        21st, 22nd, 23rd, 24th - 29th (similarly for 30s - 90s)
        110th - 119th (and for all "teens")
        121st, 122nd, 123rd, 124th - 129th

I think you see the trend.  The current code works fine except that it
produces:

        111st, 112nd, 113rd, 114th - 119th
        211st, 212nd, 213rd, 214th - 219th ... and so on.

Without knowing anything about what's supported (and what isn't) in the usual
I18N libraries, should this type of behaviour be defined within the locales?

CPP) to create platform independent files. Unfortunately, that means that
every config.status (or configure) run invariably causes a relink of the
postmaster and also that we can't put these files in the distribution
(usefully). So we make it a little smarter: when the output files already
exist and it notices that it would recreate them in identical form, it
doesn't touch them. In order to avoid re-running the make rule all the time
we update a timestamp file instead.

Update release_prep accordingly. Also make Gen_fmgrtab.sh use the awk that
is detected at configure time, not necessarily named `awk' and have it check
for exit statuses a little better.

In other news... Remove USE_LOCALE from the templates, it was set to `no'
everywhere anyway. Also remove YACC and YFLAGS from the templates, configure
is smart enough to find bison or yacc itself. Use AC_PROG_YACC for that
instead of the hand-crafted code. Do not set YFLAGS to `-d'. The make rules
that need this flag should explicitly invoke it. YFLAGS should be a user
variable. Update the makefiles to that effect.
