discussion on pgsql-hackers-win32 list. Documentation still needs to
be tweaked --- I'm not sure how to refer to the APPDATA folder in
user documentation.

Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...

that is, files are sought in the same directory as the referencing file.
Also allow absolute paths in @file constructs. Improve documentation
to actually say what is allowed in an included file.
numbering is different than TO_CHAR's ditto. EXTRACT starts at 0==Sunday
while TO_CHAR starts at 1==Sunday.
A suggestion for two documentation notes is attached as a patch to
current CVS HEAD.

several reports of users being confused when they attempt to use ELSEIF
and run into trouble due to PL/PgSQL's lax parser. The parser will be
improved for 8.1, but we can fix most of the problem by allowing ELSEIF
for now.

reasons I outlined in pghackers a few days ago.
Also, undo someone's overly optimistic decision to reduce tuple state
checks from if (...) elog() to Asserts. If I trusted this code more,
I might think it was a good idea to disable these checks in production
installations. But I don't.
a relation's number of blocks, rather than the possibly-obsolete value
in pg_class.relpages. Scale the value in pg_class.reltuples correspondingly
to arrive at a hopefully more accurate number of rows. When pg_class
contains 0/0, estimate a tuple width from the column datatypes and divide
that into current file size to estimate number of rows. This improved
methodology allows us to jettison the ancient hacks that put bogus default
values into pg_class when a table is first created. Also, per a suggestion
from Simon, make VACUUM (but not VACUUM FULL or ANALYZE) adjust the value
it puts into pg_class.reltuples to try to represent the mean tuple density
instead of the minimal density that actually prevails just after VACUUM.
These changes alter the plans selected for certain regression tests, so
update the expected files accordingly. (I removed join_1.out because
it's not clear if it still applies; we can add back any variant versions
as they are shown to be needed.)

operations are now run as subtransactions, so that errors in them
can be reported as ordinary Perl or Tcl errors and caught by the
normal error handling convention of those languages. Also do some
minor code cleanup in pltcl.c: extract a large chunk of duplicated
code in pltcl_SPI_execute and pltcl_SPI_execute_plan into a shared
subroutine.
plain SUSET instead. Also delay processing of options received in
client connection request until after we know if the user is a superuser,
so that SUSET values can be set that way by legitimate superusers.
