make sure that we are using the right #defines in pgmodule.c but the
OIDs are never actually expected to change.

broken, and its impossible to make a shared library when compiling with
both CCDLFLAGS and LDDLFAGS, you have to pick one or the other.

around.  I tested this patch under Cygwin and Linux.

Note that I only changed dblink's Makefile in the most minimal way
to fix the link problem under Cygwin (i.e., use the link rule from
Makefile.shlib instead).  dblink's Makefile should probably be further
patched to be consistent with the other PostgreSQL Makefiles.

tests to return the correct results per SQL9x when given NULL inputs.
Reimplement these tests as well as IS [NOT] NULL to have their own
expression node types, instead of depending on special functions.
From Joe Conway, with a little help from Tom Lane.

SI messages now include the relevant database OID, so that operations
in one database do not cause useless cache flushes in backends attached
to other databases.  Declare SI messages properly using a union, to
eliminate the former assumption that Oid is the same size as int or Index.
Rewrite the nearly-unreadable code in inval.c, and document it better.
Arrange for catcache flushes at end of command/transaction to happen before
relcache flushes do --- this avoids loading a new tuple into the catcache
while setting up new relcache entry, only to have it be flushed again
immediately.

Quick hack -- need to decide which header should include the other.

1) ERRORs cause an SQL_ERROR and the SQLSTATE='S1000'.
2) NOTICEs cause an SQL_SUCCESS_WITH_INFO and the succeeding
   SQLError() returns the NOTICE message.

Here is Tomified version of my 2 pending patches.
Dropped the set_.._real change as it is not needed.
Desc would be:

modifiable repositories, I have a clean untrusted plperl patch to offer
you :)

Highlights:
* There's one perl interpreter used for both trusted and untrusted
procedures. I do think its unnecessary to keep two perl
interpreters around. If someone can break out from trusted "Safe" perl
mode, well, they can do what they want already. If someone disagrees, I
can change this.

* Opcode is not statically loaded anymore. Instead, we load Dynaloader,
which then can grab Opcode (and anything else you can 'use') on its own.

* Checked to work on FreeBSD 4.3 + perl 5.5.3 , OpenBSD 2.8 + perl5.6.1,
RedHat 6.2 + perl 5.5.3

* Uses ExtUtils::Embed to find what options are necessary to link with
perl shared libraries

* createlang is also updated, it can create untrusted perl using 'plperlu'

* Example script (assuming you have Mail::Sendmail installed):
create function foo() returns text as '
         use Mail::Sendmail;

         %mail = ( To      => q(you@yourname.com),
                   From    => q(me@here.com),
                   Message => "This is a very short message"
                  );
         sendmail(%mail) or die $Mail::Sendmail::error;
return          "OK. Log says:\n", $Mail::Sendmail::log;
' language 'plperlu';

Cygwin with the possible exception of mSQL-interface.  Since I don't
have mSQL installed, I skipped this tool.

Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.

I tested the build aspect of this patch under Cygwin and Linux without
any ill affects.  Note that I did not actually attempt to test the code
for functionality.

The procedure to apply the patch is as follows:

    $ # save the attachment as /tmp/contrib.patch
    $ # change directory to the top of the PostgreSQL source tree
    $ patch -p0 </tmp/contrib.patch

   - fixed dblink invalid pointer causing corrupt elog message
   - fixed dblink_tok improper handling of null results
   - fixed examples in README.dblink

plus a few trivial improvements in wording.

functions to clear date cache.  Allow regression tests to pass when
timezone set.

pgsql_tmp.

CatalogCacheFlushRelation (formerly called SystemCacheRelationFlushed)
how to distinguish tuples it should flush from those it needn't; this
means a relcache flush event now only removes the catcache entries
it ought to, rather than zapping the caches completely as it used to.
Testing with the regression tests indicates that this considerably
improves the lifespan of catcache entries.  Also, rearrange catcache
data structures so that the limit on number of cached tuples applies
globally across all the catcaches, rather than being per-catcache.
It was a little silly to have the same size limit on both, say,
pg_attribute caches and pg_am caches (there being only four possible
rows in the latter...).  Doing LRU removal across all the caches
instead of locally in each one should reduce cache reload traffic
in the more heavily used caches and improve the efficiency of
cache memory use.

TopTransactionContext, rather than using Dllist.  This simplifies and
speeds up the code, and eliminates a former risk of coredump when
out of memory (since the old code didn't bother to check for malloc
failure).  It also moves us one step closer to retiring Dllist...

detected sooner in backend startup, and is treated as an expected error
(it gives 'Sorry, too many clients already' now).  This allows us not
to have to enforce the MaxBackends limit exactly in the postmaster.
Also, remove ProcRemove() and fold its functionality into ProcKill().
There's no good reason for a backend not to be responsible for removing
its PROC entry, and there are lots of good reasons for the postmaster
not to be touching shared-memory data structures.

rules and triggers by OID.  So, even though we have no cross-references
in the system catalogs to pg_rewrite.oid or pg_trigger.oid, we'd better
have unique indexes on them.  Put back pg_rewrite_oid_index, which I
mistakenly removed a few days ago, and add pg_trigger_oid_index.

Thanks to Steve McClure <smcclure@racemi.com> for the patch.

pg_stats to provide controlled (and, hopefully, more readable) access
to statistics.  Comments on definition of pg_stats welcome.
I didn't force initdb, but the rules regress test will fail until you
do one.

I didn't force initdb, but the additions to the 'privileges' regress
test won't pass until you do one.
