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).
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit
logic in libpq.
. replace CREATE OR REPLACE AGGREGATE with a separate DROP and CREATE
. add DROP for all CREATE OPERATORs
. use IMMUTABLE and STRICT instead of WITH (isStrict)
. add IMMUTABLE and STRICT to int_array_aggregate's accumulator function

Create objects in public schema.
Make spacing/capitalization consistent.
Remove transaction block use for object creation.
Remove unneeded function GRANTs.
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.
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.

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.
