bitmap, if present).
Per Tom Lane's suggestion the information whether a tuple has an oid
or not is carried in the tuple descriptor. For debugging reasons
tdhasoid is of type char, not bool. There are predefined values for
WITHOID, WITHOUTOID and UNDEFOID.
This patch has been generated against a cvs snapshot from last week
and I don't expect it to apply cleanly to current sources. While I
post it here for public review, I'm working on a new version against a
current snapshot. (There's been heavy activity recently; hope to
catch up some day ...)
This is a long patch; if it is too hard to swallow, I can provide it
in smaller pieces:
Part 1: Accessor macros
Part 2: tdhasoid in TupDesc
Part 3: Regression test
Part 4: Parameter withoid to heap_addheader
Part 5: Eliminate t_oid from HeapTupleHeader
Part 2 is the most hairy part because of changes in the executor and
even in the parser; the other parts are straightforward.
Up to part 4 the patched postmaster stays binary compatible to
databases created with an unpatched version. Part 5 is small (100
lines) and finally breaks compatibility.

structure.
Now includes the following new fields:
integer/float date/time storage
maximum length of names (+1; they must also include a null termination)
maximum number of function arguments
maximum length of locale name
Copy this directory to contrib/dbsize in your PostgreSQL source tree.
Then just run make; make install. Finally, load the functions into any
database using dbsize.sql.
When computing the size of a table, it does not include TOAST or index
disk space.
Fixed bug with '=' operator for gist__int_ops and
define '=' operator for gist__intbig_ops opclass.
Now '=' operator is consistent with standard 'array' type.
Thanks Achilleus Mantzios for bug report and suggestion.

yesterday's proposal to pghackers. Also remove unnecessary parameters
to heap_beginscan, heap_rescan. I modified pg_proc.h to reflect the
new numbers of parameters for the AM interface routines, but did not
force an initdb because nothing actually looks at those fields.
per pghackers discussion. Add some more typsanity tests, and clean
up some problems exposed thereby (broken or missing array types for
some built-in types). Also, clean up loose ends from unknownin/out
patch.
postgres command line utilites e.g. supports -U, -p, -h, -?, -v, password
prompt and has a "test mode". In test mode, no large objects are removed,
just reported.

objections.
Major changes:
- removed cursor wrap around input sql to allow for remote
execution of INSERT/UPDATE/DELETE
- dblink now returns a resource id instead of a real pointer
- added several utility functions
I'm still hoping to add explicit cursor open/fetch/close support before
7.3 is released, but I need a bit more time on that.
On a somewhat unrelated topic, I never got any feedback on the
unknownin/out patch and the mb_substring patch. Is there anything else I
need to do to get those applied?

an 'opclass owner' column in pg_opclass. Nothing is done with it at
present, but since there are plans to invent a CREATE OPERATOR CLASS
command soon, we'll probably want DROP OPERATOR CLASS too, which
suggests that a notion of ownership would be a good idea.
sequence functions how to cope with qualified names. Same code is
also used for int4notin, currtid_byrelname, pgstattuple. Also,
move TOAST tables into special pg_toast namespace.

Sorry Bruce, I was unclear. I have attached patch to Readme.tsearch
Also, It'd be worth to mention in Changes to point users of tsearch
about importang upgrade notices.

o Change all current CVS messages of NOTICE to WARNING. We were going
to do this just before 7.3 beta but it has to be done now, as you will
see below.
o Change current INFO messages that should be controlled by
client_min_messages to NOTICE.
o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc.
to always go to the client.
o Remove INFO from the client_min_messages options and add NOTICE.
Seems we do need three non-ERROR elog levels to handle the various
behaviors we need for these messages.
Regression passed.
CVS. It fix english stemmer's problem with ending words like
'technology'.
We have found one more bug in english stemmer. The bug is with
'irregular' english words like 'skies' -> 'sky'. Please, apply attached
cumulative patch to 7.2.1 and current CVS instead previous one.
Thank to Thomas T. Thai <tom@minnesota.com> for hard testing. This kind
of bug has significance only for dump/reload database and viewing, but
searching/indexing works right.

malloc()'s. This isn't too serious (because oid2name is a short-lived
utility, so the memory will soon be returned to the OS on process
termination), but I still think it's poor style.
This patch changes oid2name so that it allocates memory on the stack
where possible and free()s the remaining heap-allocated memory. The
patch also fixes a typo a comment and adds 'const' qualifiers to a few
'char *' function parameters.
