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.

qualified operator names directly, for example CREATE OPERATOR myschema.+
( ... ). To qualify an operator name in an expression you need to write
OPERATOR(myschema.+) (thanks to Peter for suggesting an escape hatch).
I also took advantage of having to reformat pg_operator to fix something
that'd been bugging me for a while: mergejoinable operators should have
explicit links to the associated cross-data-type comparison operators,
rather than hardwiring an assumption that they are named < and >.

was in the thread "make BufferGetBlockNumber() a macro". Tom
objected to the original patch, so I prepared a new one which
doesn't change BufferGetBlockNumber() into a macro, it just
cleans up some comments and fixes an assertion. The patch
is attached.

The indexes on most system catalogs are named with the suffix "_index";
not so with TOAST table indexes, which use "_idx". This trivial patch
changes TOAST table index names to use the "_index" suffix for
consistency.

In summary, if a software writer implements timer events or other events
which generate a signal with a timing fast enough to occur while libpq
is inside connect(), then connect returns -EINTR. The code following
the connect call does not handle this and generates an error message.
The sum result is that the pg_connect() fails. If the timer or other
event is right on the window of the connect() completion time, the
pg_connect() may appear to work sporadically. If the event is too slow,
pg_connect() will appear to always work and if the event is too fast,
pg_connect() will always fail.

selected as the creation target namespace; to make that happen, you
must explicitly set search_path that way. This makes initdb a hair
more complex but seems like a good safety feature.

have been divided according to the type of object manipulated - so ALTER
TABLE code is in tablecmds.c, aggregate commands in aggregatecmds.c and
so on.
A few common support routines remain in define.c (prototypes in
src/include/commands/defrem.h).
No code has been changed except for includes to reflect the new files.
The prototypes for aggregatecmds.c, functioncmds.c, operatorcmds.c,
and typecmds.c remain in src/include/commands/defrem.h.

Add Mandrake installation layout to directories to check for stylesheets.
Allow documentation build to proceed if stylesheets were not found, in case
the stylesheets might be found through the SGML catalog mechanism.

some old code to add PK constraints to CREATE TABLE. That stuff
had been removed as part of my original patch for pg_dump a
little while ago.
The attached patch fixes this by removing (again :-) ) the
code in dumpTables() to perform PK creation during CREATE
TABLE. I briefly tested it locally and it fixes both of
Tom's test cases.
Please apply.
Cheers,
Neil

for Solaris on SPARC. Scott Brunza (sbrunza@sonalysts.com) gets
credit for identifying the issue, making the change, and doing
the regression tests.
Earlier testing on 7.2rc2 and 7.2 showed performance gains of
1% to 10% on pgbench, osdb-pg, and some locally developed apps.

the libpgtcl "pg_execute" command. This was mentioned on
pgsql-interfaces on Mar 3. I am posting it here in the hope that someone
will check to see if it makes sense and is correct SGML-wise. I did run
it through jade, but this is my first try at this sort of thing.

entries, per pghackers discussion. This fixes aggregates to live in
namespaces, and also simplifies/speeds up lookup in parse_func.c.
Also, add a 'proimplicit' flag to pg_proc that controls whether a type
coercion function may be invoked implicitly, or only explicitly. The
current settings of these flags are more permissive than I would like,
but we will need to debate and refine the behavior; for now, I avoided
breaking regression tests as much as I could.
