-hackers a couple days ago.
Notes/caveats:
- added regression tests for the new functionality, all
regression tests pass on my machine
- added pg_dump support
- updated PL/PgSQL to support per-statement triggers; didn't
look at the other procedural languages.
- there's (even) more code duplication in trigger.c than there
was previously. Any suggestions on how to refactor the
ExecXXXTriggers() functions to reuse more code would be
welcome -- I took a brief look at it, but couldn't see an
easy way to do it (there are several subtly-different
versions of the code in question)
- updated the documentation. I also took the liberty of
removing a big chunk of duplicated syntax documentation in
the Programmer's Guide on triggers, and moving that
information to the CREATE TRIGGER reference page.
- I also included some spelling fixes and similar small
cleanups I noticed while making the changes. If you'd like
me to split those into a separate patch, let me know.

with regard to the extra_float_digits setting.
Since builtins.h was already included, I just deleted the extern
statement (and accompaning comments).

one more row from the subplan than the COUNT would appear to require.
This costs a little more logic but a number of people have complained
about the old implementation.

documentation about the AT TIME ZONE construct. Update some other
date/time documentation that seemed out of date for 7.3.

in SIBackendInit(); improve comments; add documentation (this part courtesy
Neil Conway).
parameter to allow it to be forced off for comparison purposes.
Add ORDER BY clauses to a bunch of regression test queries that will
otherwise produce randomly-ordered output in the new regime.
on a preparedStatement would reset the prepared statment causing subsequent
uses of the preparedStatement to fail (i.e. the following series of calls
would fail: addBatch() executeBatch() addBatch() executBatch()). This is
a regression from 7.2 where this worked correctly. The regression test has
also been modified to explicitly test for this case.

of groups produced by GROUP BY. This improves the accuracy of planning
estimates for grouped subselects, and is needed to check whether a
hashed aggregation plan risks memory overflow.
"canceled", so I changed the one remaining usage of the British
spelling ("cancelled") over to the former, and updated the translation
files appropriately.

The code was not making TupleConstr structs for such catalogs in
several places; with the consequence that the not-null constraint
wasn't actually enforced. With this change,
INSERT INTO pg_proc VALUES('sdf');
generates a 'Fail to add null value' error instead of a core dump.
