query that uses it. This ensures that triggers will be applied consistently
throughout a query even if someone commits changes to the relation's
pg_class.reltriggers field meanwhile. Per crash report from Laurette Cisneros.
While at it, simplify memory management in relcache.c, which no longer
needs the old hack to try to keep trigger info in the same place over
a relcache entry rebuild. (Should try to fix rd_att and rewrite-rule
access similarly, someday.) And make RelationBuildTriggers simpler and
more robust by making it build the trigdesc in working memory and then
CopyTriggerDesc() into cache memory.
- Wrap them in the <database class="table"> tags, since thats what they
are (no markup rules for this, so it inherits from parent -- no style
change)
- Mention that pg_database, pg_shadow, and pg_group are global, and the
rest are local to the specific DB. (I believe this is correct).

Ok, new patch.

ANALYZE is not quite clear when branches of the query are never
executed. So this tiny patch fixes that.
The patch is attached and can also be found at:

1) pltcl:
Add SPI_freetuptable() calls to avoid memory leaks (Me + Neil Conway)
Change sprintf()s to snprintf()s (Neil Conway)
Remove header files included elsewhere (Neil Conway)
2)plpython:
Add SPI_freetuptable() calls to avoid memory leaks
Cosemtic change to remove a compiler warning
Notes:
I have tested pltcl.c for
a) the original leak problem reported for the repeated call of spi_exec
in a TCL fragment
and
b) the subsequent report resulting from the use of spi_exec -array
in a TCL
fragment.
The plpython.c patch is exactly the same as that applied to make
revision 1.23,
the plpython_schema.sql and feature.expected sections of the patch are
also the
same as last submited, applied and subsequently reversed out. It remains
untested by me (other than via make check). However, this should be safe
provided PyString_FromString() _copies_ the given string to make a
PyObject.

contrib/contrib-global.mk library and _generally_ behave like
Makefiles for other contrib modules.
Besides it fixes Perl's interpolation of $libdir variable, which
should be passed to backend instead. This patch is done against
PostgreSQL 7.3b2
Besides, I want to thank Peter Eisentraut for his very friendly and
helpful attitude and politely ask him to check whether contrib
modules actually continue to work after he implements another
major change to their build process.

Attached is a patch to fix the mb linking problems on AIX. As a nice side effect
it reduces the duplicate symbol warnings to linking libpq.so and libecpg.so
(all shlibs that are not postmaster loadable modules).
Please apply to current (only affects AIX).
The _LARGE_FILES problem is unfortunately still open, unless Peter
has fixed it per his recent idea.

Nah. I don't think it's worth it: I had forgotten that older versions
should be supported. I just left the code as is and added a
version-specific test.
This patch allows pg_dump to dump correctly local definition of columns.
In particular,
CREATE TABLE p1 (f1 int, f2 int);
CREATE TABLE p2 (f1 int);
CREATE TABLE c () INHERITS (p1, p2);
ALTER TABLE ONLY p1 DROP COLUMN f1;
CREATE TABLE p3 (f1 int);
CREATE TABLE c2 (f1 int) INHERITS (p3);
Will be dumped as
CREATE TABLE p1 (f2 int);
CREATE TABLE p2 (f1 int);
CREATE TABLE c (f1 int) INHERITS (p1, p2);
CREATE TABLE c2 (f1 int) INHERITS (p3);
(Previous version will dump
CREATE TABLE c () INHERITS (p1, p2)
CREATE TABLE c2 () INHERITS (p3) )

into postgres.c; make sure it happens for all cases that seem to need it.
Perhaps it would be better to explicitly exclude just a few utility
statement types from setting a snapshot?
in our write/flush operation any WAL entries that got queued while we
were waiting to get the WALWriteLock. This improves throughput when
transactions are small enough that several can be committed per WAL
write (ie, per disk revolution).
