remove unnecessary inclusions.

with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

HeapTupleHeaderData in setter and getter macros called
HeapTupleHeaderGetXmin, HeapTupleHeaderSetXmin etc.

It also introduces a "virtual" field xvac by defining
HeapTupleHeaderGetXvac and HeapTupleHeaderSetXvac.  Xvac is used by
VACUUM, in fact it is stored in t_cmin.

As proof of concept, provide an alternate implementation based on POSIX
semaphores.  Also push the SysV shared-memory implementation into a
separate file so that it can be replaced conveniently.

still needed because only removed in 7.4.

allows plperl routines to return NULL as intended.

REPLACE FUNCTION.  Clean up typlen/typmod errors inherited from pltcl.

lookup info in the relcache for index access method support functions.
This makes a huge difference for dynamically loaded support functions,
and should save a few cycles even for built-in ones.  Also tweak dfmgr.c
so that load_external_function is called only once, not twice, when
doing fmgr_info for a dynamically loaded function.  All per performance
gripe from Teodor Sigaev, 5-Oct-01.

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';

in plpgsql: they fail for datatypes that have old-style I/O functions
due to caching FmgrInfo structs with wrong fn_mcxt lifetime.

Although the plpython fix seems straightforward, I can't check it here
since I don't have Python installed --- would someone check it?

or return type.

in pghackers list.  Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention.  pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'.  A newstyle function must be identified
by an associated info routine.  See src/backend/utils/fmgr/README.

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.

Devel::PPPort instead.  Thanks to Gilles Darold for doing the legwork.

7.0.2 release. Sorry, if that's fixed ages ago - I don't track
development versions of PostgreSQL.

Patch is just a little bit tested (some valid functions created and
successfully run as well as some erroneous ones created and emitted proper
error messages when used).

My platform is FreeBSD 5.0-CURRENT (with perl 5.6.0 provided in the
base system).

one of updating the whole text datatype, but there are so dang many
calls of these two routines that it seems worth a separate commit.

inputs have been converted to newstyle.  This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters.  Still
more to do for the Alpha port however.

fmgr_faddr() in favor of new-style calls.  Lots of cleanup of
sloppy casts to use XXXGetDatum and DatumGetXXX ...

CurrentTriggerData is history.

key call sites are changed, but most called functions are still oldstyle.
An exception is that the PL managers are updated (so, for example, NULL
handling now behaves as expected in plperl and plpgsql functions).
NOTE initdb is forced due to added column in pg_proc.

print OIDs as %u not %d.

followed by 'extern void foo() { ... }'.

3 new files and two patches for the plperl subdir.

These changes add the ability for plperl functions
to call 'elog'. It also sets up the frame work to
allow me to add access to the SPI functions.

functions, which would lead to trouble with datatypes that paid attention
to the typelem or typmod parameters to these functions.  In particular,
incorrect code in pg_aggregate.c explains the platform-specific failures
that have been reported in NUMERIC avg().

Make all system indexes unique.
Make all cache loads use system indexes.
Rename *rel to *relid in inheritance tables.
Rename cache names to be clearer.

Fewer calls to nameout.

Better use of RelationGetRelationName.
