The patch enables the mips2 ISA for the ll/sc operations, and then restores
it when done.  The kernel/libc emulation code will take over on CPUs without
ll/sc, and on CPUs with it, it'll use the operations provided by the CPU.

Combined with the earlier fix (removing -mips2), postgresql builds again on
mips and mipsel.  The patch is against 7.2-7.

INSERT statements to the planner.  Taking it out of the parser was right
(so that defaults don't get into stored rules), but it has to happen
before rewrite rule expansion, else references to NEW.field behave
incorrectly.  Accordingly, add a step to the rewriter to insert defaults
just before rewrite-rule expansion.

> * -Add new pg_proc cachable settings to specify whether function can be

volatile), rather than the old cachable/noncachable distinction.  This
allows indexscan optimizations in many places where we formerly didn't.
Also, add a pronamespace column to pg_proc (it doesn't do anything yet,
however).

< 	o Allow cursors to be DECLAREd/OPENed/CLOSEed outside transactions

* -Allow user/group names to be specified directly in pg_hba.conf (Bruce)

records containing apostrophes in text fields without altering the appearance
of the entry in the GUI interface (by copying the fldval to fldvalfixed).

This will alleviate the need for users to create a record and then go back to
edit apostrophes into the text they entered.

Allow samegroup in database column to match group name matching dbname
Removal of secondary password files
Remove pg_passwd utility
Lots of code cleanup in user.c and hba.c
New data/global/pg_pwd format
New data/global/pg_group file

in the backend; let's not reintroduce any...

per recent discussion on pghackers.  Also, fix PGSTAT code to report
errors via elog, not scribbling directly on stderr.

Patch against 7,2 submitted for comment.

This seems to work just fine; Now, when our users submit a 2 hour
query with four million row sorts by accident, then cancel it 30 seconds
later, it doesn't bog down the server ...

as argument for nextval().

Removed error message that was incorectly being issued.  This fixes a problem reported a few months ago where a select in a rule was causing an insert statement to return a result set which the code was explicitly prohibiting.

wrapped-around databases.  The unvacuumed databases might be fine, or
they might not, but things will definitely not be fine if we remove the
wrong CLOG segments.  Per trouble report from Gary Wolfe, 1-Apr-2002.

depend on this rather than the trigger argument strings to locate the
other relation to test.  This makes RI triggers function properly in
the presence of schemas and temp tables.  Along the way, fix bogus lack
of locking in RI triggers, handle quoting of names fully correctly,
compute required sizes of query buffers with some semblance of accuracy.

bootstrap/bootparse.y, so that recent versions of bison don't emit a

path.  The default behavior if no per-user schemas are created is that
all users share a 'public' namespace, thus providing behavior backwards
compatible with 7.2 and earlier releases.  Probably the semantics and
default setting will need to be fine-tuned, but this is a start.

2) Implement some options for SQLGetDescField().
3) Handle *Inifinity* timestamp for SQL_C_CHAR type output.
4) Separate Unicode conversions from common implementations.
5) Improve internal parse_statement() function.

catalog namespace.  This will not do as a production solution because
the interpretation of RI trigger arguments will vary depending on the
current namespace search path.  I'm just putting it in so that the RI
regression tests don't fail while schema development proceeds.  We
must find a better answer before 7.3 can be released.

consistency with renameatt.

temp table entries in pg_class have the names the user would expect.

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.
