having names conflicting with system objects will work --- the search
path is now user-schema, pg_catalog rather than implicitly the other way
around. Note this requires being careful to explicitly qualify references
to system names whenever pg_catalog is not first in the search path.
Also, add support for dumping ACLs of schemas.
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.
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).
their names from pg_class. This considerably reduces the window wherein
someone could DROP or ALTER a table that pg_dump is intending to dump.
Not a perfect solution, but definitely an improvement. Per complaints
from Marc Fournier; patch by Brent Verner with some kibitzing by Tom Lane.
'aggname (aggtype)'. The old syntax 'aggname aggtype' is still accepted
for backwards compatibility. Fix pg_dump, which was actually broken for
most cases of user-defined aggregates. Clean up error messages associated
with these commands.
pg_get_indexdef() function, rather than reaching into the system catalogs
for itself. This eliminates a fair amount of redundant code. Also,
since I just changed pg_get_indexdef() to suppress display of default
index opclasses, this will mean that 7.2 and later dumps will not mention
opclasses unless they are non-default opclasses. Should make life easier
for future index opclass reorganizations.
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.
Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.
initdb forced.
Dump the alignment and storage information for user-defined types (how'd
that manage to slip through the cracks?), and don't dump 'shell' types
that don't have typisdefined set. Fix badly broken logic for dependencies
of type definitions (did not work for more than one user-defined type...).
Avoid memory leakage within pg_dump by being more careful to release
storage used by PQExpBuffer objects.
Note: I didn't force an initdb, figuring that one today was enough.
However, there is a new function in pg_proc.h, and pg_dump won't be
able to dump partial indexes until you add that function.
--verbose messages, which had not been considered so far. Output to the
terminal should okay now; comments written into the dump are still English
only, which may or may not be the desirable thing.
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
cloned, rather than always cloning template1. Modify initdb to generate
two identical databases rather than one, template0 and template1.
Connections to template0 are disallowed, so that it will always remain
in its virgin as-initdb'd state. pg_dumpall now dumps databases with
restore commands that say CREATE DATABASE foo WITH TEMPLATE = template0.
This allows proper behavior when there is user-added data in template1.
initdb forced!
- Use symbols for tests on relkind (ie. use RELKIND_VIEW, not 'v')
- Fix bug in support for -b option (== --blobs).
- Dump views as views (using 'create view').
- Remove 'isViewRule' since we check the relkind when getting tables.
- Now uses temp table 'pgdump_oid' rather than 'pg_dump_oid' (errors otherwise).
- Added extra param for specifying handling of OID=0 and which typename to output.
- Fixed bug in SQL scanner when SQL contained braces. (in rules)
- Use format_type function wherever possible
There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner. Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.
Also, enable new LIKE selectivity estimators by default. Unrelated
change, but as long as I had to force initdb anyway...
Attached is a patch which patches cleanly against the Sunday afternoon
snapshot. It modifies pg_dump to dump COMMENT ON statements for
user-definable descriptions. In addition, it also modifies comment.c so
that the operator behavior is as Peter E. would like: a comment on an
operator is applied to the underlying function.
Thanks,
Mike Mascari
oidvector/int2vector. pg_dump code was assuming that it would see
exactly FUNC_MAX_ARGS integers in the string returned by the backend.
That's no longer true. (Perhaps that change wasn't such a good idea
after all --- will it break any other applications??)
I finally got around to schlepping through pg_dump, to finish what I started
about three months (or more) ago. Attached is a gzipped diff file to apply
in the bin/pg_dump directory. This should remove all string length
dependencies, except one, which I'm working on. It has been through some
rudimentary unit testing, but that's about it, so if any of you would give
it a more strenuous run-through, I'd be grateful for the feedback.
Cheers...
Ansley, Michael
Make all system indexes unique.
Make all cache loads use system indexes.
Rename *rel to *relid in inheritance tables.
Rename cache names to be clearer.
