getting rid of numerous ad-hoc versions that have popped up in various
places.  Shortens code and avoids conflict with Windows min() and max()
macros.

pghackers proposal of 8-Nov.  All the existing cross-type comparison
operators (int2/int4/int8 and float4/float8) have appropriate support.
The original proposal of storing the right-hand-side datatype as part of
the primary key for pg_amop and pg_amproc got modified a bit in the event;
it is easier to store zero as the 'default' case and only store a nonzero
when the operator is actually cross-type.  Along the way, remove the
long-since-defunct bigbox_ops operator class.

Remove the 'strategy map' code, which was a large amount of mechanism
that no longer had any use except reverse-mapping from procedure OID to
strategy number.  Passing the strategy number to the index AM in the
first place is simpler and faster.
This is a preliminary step in planned support for cross-datatype index
operations.  I'm committing it now since the ScanKeyEntryInitialize()
API change touches quite a lot of files, and I want to commit those
changes before the tree drifts under me.

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.

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.

assert_test() functions --- these weren't accomplishing much except to
render the whole module un-loadable ...

Does not work since it fetches one byte beyond the source data, and when
the phase of the moon is wrong, the source data is smack up against the
end of backend memory and you get SIGSEGV.  Don't laugh, this is a fix
for an actual user bug report.

the src/include tree, so that -I backend is no longer necessary anywhere.
Also, clean up some bit rot in contrib tree.

        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?

additional argument specifying the kind of lock to acquire/release (or
'NoLock' to do no lock processing).  Ensure that all relations are locked
with some appropriate lock level before being examined --- this ensures
that relevant shared-inval messages have been processed and should prevent
problems caused by concurrent VACUUM.  Fix several bugs having to do with
mismatched increment/decrement of relation ref count and mismatched
heap_open/close (which amounts to the same thing).  A bogus ref count on
a relation doesn't matter much *unless* a SI Inval message happens to
arrive at the wrong time, which is probably why we got away with this
sloppiness for so long.  Repair missing grab of AccessExclusiveLock in
DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi.
Recommend 'make clean all' after pulling this update; I modified the
Relation struct layout slightly.
Will post further discussion to pghackers list shortly.

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.

From: Massimo Dal Zotto <dz@cs.unitn.it>

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.
