the decision not to make renamerel() update the sequence name that
is stored within sequences themselves (thanks to Tom Lane), and adds
some rudimentary regression tests for ALTER TABLE ... RENAME on
non-table relations.

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.
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).
A new pg_hba.conf column, USER
Allow specifiction of lists of users separated by commas
Allow group names specified by +
Allow include files containing lists of users specified by @
Allow lists of databases, and database files
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

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.
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.
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.

also used for int4notin, currtid_byrelname, pgstattuple. Also,
move TOAST tables into special pg_toast namespace.

path yet, and not all operations work yet on tables outside the system
namespace.

it will no longer be a useful unique identifier of relations;
we want to encourage people to rely on the relation OID instead.
Further work on dumping qual expressions in EXPLAIN, too.

necessary no matter what in the schema environment, and simply getting
rid of the name-based interface entirely seems like the best way.

names, just drop 'em on the floor; but you can enter schema-compatible
command syntax, and there's even a primitive CREATE SCHEMA command.
No doc updates yet, except to note that you can now extract a field
from a function-returning-row's result with (foo(...)).fieldname.
in the current code, the authentication logic (check user, check the
relation we're operating on, etc) is done in tcop/utility.c, whereas the
actual TRUNCATE command in done in TruncateRelation() in
commands/createinh.c (which is really just a wrapper over
heap_truncate() in catalog/heap.c). This patch moves the authentication
logic into TruncateRelation(), as well as making some minor code
cleanups.

before a data item is now always skipped, rather than only sometimes.
Backslashes not within double-quoted text are treated reasonably, as
are multiple sequences of quoted text in a single data item. But it
still seems rather prone to misbehavior if the input is not completely
syntactically correct --- in particular, garbage following a right brace
will be ignored.
per recent pghackers discussion: force a new WAL record at first nextval
after a checkpoint, and ensure that xlog is flushed to disk if a nextval
record is the only thing emitted by a transaction.
