blanks, in hopes of reducing the surprise factor for newbies. Remove
redundant operators for VARCHAR (it depends wholly on TEXT operations now).
Clean up resolution of ambiguous operators/functions to avoid surprising
choices for domains: domains are treated as equivalent to their base types
and binary-coercibility is no longer considered a preference item when
choosing among multiple operators/functions. IsBinaryCoercible now correctly
reflects the notion that you need *only* relabel the type to get from type
A to type B: that is, a domain is binary-coercible to its base type, but
not vice versa. Various marginal cleanup, including merging the essentially
duplicate resolution code in parse_func.c and parse_oper.c. Improve opr_sanity
regression test to understand about binary compatibility (using pg_cast),
and fix a couple of small errors in the catalogs revealed thereby.
Restructure "special operator" handling to fetch operators via index opclasses
rather than hardwiring assumptions about names (cleans up the pattern_ops
stuff a little).

array header, and to compute sizing and alignment of array elements
the same way normal tuple access operations do --- viz, using the
tupmacs.h macros att_addlength and att_align. This makes the world
safe for arrays of cstrings or intervals, and should make it much
easier to write array-type-polymorphic functions; as examples see
the cleanups of array_out and contrib/array_iterator. By Joe Conway
and Tom Lane.

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.

1. Distinguish cases where a Datum representing a tuple datatype is an OID
from cases where it is a pointer to TupleTableSlot, and make sure we use
the right typlen in each case.
2. Make fetchatt() and related code support 8-byte by-value datatypes on
machines where Datum is 8 bytes. Centralize knowledge of the available
by-value datatype sizes in two macros in tupmacs.h, so that this will be
easier if we ever have to do it again.

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.

Remove a bunch of crufty code for large-object-based arrays, which is
superseded by TOAST and likely hasn't worked in a long time anyway.
Clean up array code a little, and in particular eliminate its habit
of scribbling on the input array (ie, modifying the input tuple :-().

this is an old patch which I have already submitted and never seen
in the sources. It corrects the datatype oids used in some iterator
functions. This bug has been reported to me by many other people.
contrib-datetime.patch
some code contributed by Reiner Dassing <dassing@wettzell.ifag.de>
contrib-makefiles.patch
fixes all my contrib makefiles which don't work with some compilers,
as reported to me by another user.
contrib-miscutil.patch
an old patch for one of my old contribs.
contrib-string.patch
a small change to the c-like text output functions. Now the '{'
is escaped only at the beginning of the string to distinguish it
from arrays, and the '}' is no more escaped.
elog-lineno.patch
adds the current lineno of CopyFrom to elog messages. This is very
useful when you load a 1 million tuples table from an external file
and there is a bad value somehere. Currently you get an error message
but you can't know where is the bad data. The patch uses a variable
which was declared static in copy.c. The variable is now exported
and initialized to 0. It is always cleared at the end of the copy
or at the first elog message or when the copy is canceled.
I know this is very ugly but I can't find any better way of knowing
where the copy fails and I have this problem quite often.
plperl-makefile.patch
fixes a typo in a makefile, but the error must be elsewhere because
it is a file generated automatically. Please have a look.
tprintf-timestamp.patch
restores the original 2-digit year format, assuming that the two
century digits don't carry much information and that '000202' is
easier to read than 20000202. Being only a log file it shouldn't
break anything.
Please apply the patches before the next scheduled code freeze.
I also noticed that some of the contribs don't compile correcly. Should we
ask people to fix their code or rename their makefiles so that they are
ignored by the top makefile?

I have updated my contrib code for version 6.5. In the attachment you will
find the directories array, datetime, miscutil, string, tools and userlocks
which replace the corresponding directories under contrib.
In contrib/tools you will find some developement scripts which I use while
hacking the sources. I hope they will be useful for some other people.
I have also added a contrib/Makefile which tries to compile and install all
the contribs. Unfortunately many of them don't have a Makefile or don't
compile cleanly.

pgsql-6.3.2. I think array_iterator is a great thing to have!!!

Here is a tar file the new directories, which substitute the old ones
in contrib. Please remove the old directories array, datetime, miscutil,
string and userlock before unpacking the tar file in contrib.
Note that as the modules are now installed in lib/modules I install all
my sql code in lib/sql. In my opinion also the other contributors should
follow these rules.

This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).
