Tom Lane 6cef5d2549 Operators live in namespaces. CREATE/DROP/COMMENT ON OPERATOR take
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 >.

Bruce Momjian bbae09c2cb CATALOG VERSION UPDATED:
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.

Tom Lane 71dc300a37 The contents of command.c, creatinh.c, define.c, remove.c and rename.c
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.

Tom Lane 9999f5a10e Checking to decide whether relations are system relations now depends
on the namespace not the name; pg_ is not a reserved prefix for table
names anymore.  From Fernando Nasser.

Bruce Momjian 50b5d4bf76 Add mention of function CREATE INDEX usage. 2002-04-11 23:20:04 +00:00
Tom Lane 902a6a0a4b Restructure representation of aggregate functions so that they have pg_proc
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.

Peter Eisentraut 25f050d90d Make sure that usesuper is always accessed through superuser(), so that the
single-user escape path always works.

Tom Lane f2d70d32eb Functions live in namespaces. Qualified function names work, eg
SELECT schema1.func2(...).  Aggregate names can be qualified at the
syntactic level, but the qualification is ignored for the moment.

Bruce Momjian 80f46fab63 This patch adds a missing heap_freetuple() to renamerel(), documents
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.

Tom Lane 4bdb4be62e Divide functions into three volatility classes (immutable, stable, and
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).

Bruce Momjian 43a3543a4e Authentication improvements:
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

Tom Lane 9c54cfb493 Fix CLOG truncation code to not do the Wrong Thing when there are already
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.

Tom Lane 1dc43ea75f Make VACUUM handle schema-qualified relation names properly. 2002-04-02 01:03:07 +00:00
Tom Lane 789ddcb5fe Add tgconstrrelid to stored Trigger structures, make RI trigger functions
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.

Tom Lane d51675169f Make renamerel take an OID, not a RangeVar, to identify the relation
to rename.  Avoids some corner-case bugs in cluster.c, improves
consistency with renameatt.

Tom Lane 5f4745adf4 Further cleanups for relations in schemas: teach nextval and other
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.

Tom Lane d67442ccfd Mop-up some infelicities in new relation lookup handling. 2002-03-29 22:10:34 +00:00
Tom Lane d5e99ab4d6 pg_type has a typnamespace column; system now supports creating types
in different namespaces.  Also, cleanup work on relation namespace
support: drop, alter, rename commands work for tables in non-default
namespaces.
2002-03-29 19:06:29 +00:00
Tom Lane 1dbf8aa7a8 pg_class has a relnamespace column. You can create and access tables
in schemas other than the system namespace; however, there's no search
path yet, and not all operations work yet on tables outside the system
namespace.

Tom Lane 10d3995057 EXPLAIN output now comes out as a query result, not a NOTICE message.
Also, fix debug logging of parse/plan trees so that the messages actually
go through elog(), not directly to stdout.

Tom Lane a25b94c080 Create the pg_namespace system catalog. Doesn't do much yet, but it's
there and CREATE SCHEMA will make entries in it...
2002-03-22 21:34:44 +00:00
Tom Lane 108a0ec87d A little further progress on schemas: push down RangeVars into
addRangeTableEntry calls.  Remove relname field from RTEs, since
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.
2002-03-22 02:56:37 +00:00
Tom Lane 56c9b73c1d Change the aclchk.c routines to uniformly use OIDs to identify the
objects to be privilege-checked.  Some change in their APIs would be
necessary no matter what in the schema environment, and simply getting
rid of the name-based interface entirely seems like the best way.
2002-03-21 23:27:25 +00:00
Tom Lane 95ef6a3448 First phase of SCHEMA changes, concentrating on fixing the grammar and
the parsetree representation.  As yet we don't *do* anything with schema
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.

Tom Lane 337b22cb47 Code review for DOMAIN patch. 2002-03-20 19:45:13 +00:00
Bruce Momjian a9819ca253 The attached patch cleans up the implementation of the TRUNCATE command;
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.

Tom Lane 01747692fe Repair two problems with WAL logging of sequence nextvalI() ops, as
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.

Bruce Momjian 31effd10fe The attached patch changes ALTER TABLE OWNER to also change the

Tom Lane 6eeb95f0f5 Restructure representation of join alias variables. An explicit JOIN
now has an RTE of its own, and references to its outputs now are Vars
referencing the JOIN RTE, rather than CASE-expressions.  This allows
reverse-listing in ruleutils.c to use the correct alias easily, rather
than painfully reverse-engineering the alias namespace as it used to do.
Also, nested FULL JOINs work correctly, because the result of the inner
joins are simple Vars that the planner can cope with.  This fixes a bug
reported a couple times now, notably by Tatsuo on 18-Nov-01.  The alias
Vars are expanded into COALESCE expressions where needed at the very end
of planning, rather than during parsing.
Also, beginnings of support for showing plan qualifier expressions in
EXPLAIN.  There are probably still cases that need work.
initdb forced due to change of stored-rule representation.

Tom Lane cf68a686a6 Fix copying/equality-check bugs in GrantStmt and ConstraintsSetStmt,

Bruce Momjian b976b8af80 Back out domain patch until it works properly. 2002-03-07 16:35:41 +00:00
Bruce Momjian 01c76f7411 Ok. Updated patch attached.
- domain.patch -> source patch against pgsql in cvs
- drop_domain.sgml and create_domain.sgml -> New doc/src/sgml/ref docs

- dominfo.txt -> basic domain related queries I used for testing
[ ADDED TO /doc]

Enables domains of array elements -> CREATE DOMAIN dom int4[3][2];

Uses a typbasetype column to describe the origin of the domain.

Copies data to attnotnull rather than processing in execMain().

Some documentation differences from earlier.

If this is approved, I'll start working on pg_dump, and a \dD <domain>
option in psql, and regression tests.  I don't really feel like doing
those until the system table structure settles for pg_type.


CHECKS when added, will also be copied to to the table attributes.  FK
Constraints (if I ever figure out how) will be done similarly.  Both
will lbe handled by MergeDomainAttributes() which is called shortly
before MergeAttributes().

Bruce Momjian 92288a1cf9 Change made to elog:
o  Change all current CVS messages of NOTICE to WARNING.  We were going
to do this just before 7.3 beta but it has to be done now, as you will
see below.

o Change current INFO messages that should be controlled by
client_min_messages to NOTICE.

o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc.
to always go to the client.

o Remove INFO from the client_min_messages options and add NOTICE.

Seems we do need three non-ERROR elog levels to handle the various
behaviors we need for these messages.

Regression passed.

Bruce Momjian 03194432de I attach a version of my toast-slicing patch, against current CVS
(current as of a few hours ago.)

This patch:

1. Adds PG_GETARG_xxx_P_SLICE() macros and associated support routines.

2. Adds routines in src/backend/access/tuptoaster.c for fetching only
necessary chunks of a toasted value. (Modelled on latest changes to
assume chunks are returned in order).

3. Amends text_substr and bytea_substr to use new methods. It now
handles multibyte cases -and should still lead to a performance
improvement in the multibyte case where the substring is near the
beginning of the string.

4. Added new command: ALTER TABLE tabname ALTER COLUMN colname SET
STORAGE {PLAIN | EXTERNAL | EXTENDED | MAIN} to parser and documented in
alter-table.sgml. (NB I used ColId as the item type for the storage
mode string, rather than a new production - I hope this makes sense!).
All this does is sets attstorage for the specified column.

4. AlterTableAlterColumnStatistics is now AlterTableAlterColumnFlags and
handles both statistics and storage (it uses the subtype code to
distinguish). The previous version of my patch also re-arranged other
code in backend/commands/command.c but I have dropped that from this
patch.(I plan to return to it separately).

5. Documented new macros (and also the PG_GETARG_xxx_P_COPY macros) in
xfunc.sgml. ref/alter_table.sgml also contains documentation for ALTER
COLUMN SET STORAGE.

Tom Lane 26ac217173 Catcaches can now store negative entries as well as positive ones, to
speed up repetitive failed searches; per pghackers discussion in late
January.  inval.c logic substantially simplified, since we can now treat
inserts and deletes alike as far as inval events are concerned.  Some
repair work needed in heap_create_with_catalog, which turns out to have
been doing CommandCounterIncrement at a point where the new relation has
non-self-consistent catalog entries.  With the new inval code, that
resulted in assert failures during a relcache entry rebuild.
2002-03-03 17:47:56 +00:00
Bruce Momjian a033daf566 Commit to match discussed elog() changes. Only update is that LOG is
now just below FATAL in server_min_messages.  Added more text to
highlight ordering difference between it and client_min_messages.

---------------------------------------------------------------------------

REALLYFATAL => PANIC
STOP => PANIC
New INFO level the prints to client by default
New LOG level the prints to server log by default
Cause VACUUM information to print only to the client
NOTICE => INFO where purely information messages are sent
DEBUG => LOG for purely server status messages
DEBUG removed, kept as backward compatible
DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added
DebugLvl removed in favor of new DEBUG[1-5] symbols
New server_min_messages GUC parameter with values:
        DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC
New client_min_messages GUC parameter with values:
        DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC
Server startup now logged with LOG instead of DEBUG
Remove debug_level GUC parameter
elog() numbers now start at 10
Add test to print error message if older elog() values are passed to elog()
Bootstrap mode now has a -d that requires an argument, like postmaster
2002-03-02 21:39:36 +00:00
Peter Eisentraut 1aac2c852a User and database-specific session defaults for run-time configuration
variables.  New commands ALTER DATABASE ... SET and ALTER USER ... SET.
2002-03-01 22:45:19 +00:00
Tom Lane 6779c55c22 Clean up BeginCommand and related routines. BeginCommand and EndCommand
are now both invoked once per received SQL command (raw parsetree) from
pg_exec_query_string.  BeginCommand is actually just an empty routine
at the moment --- all its former operations have been pushed into tuple
receiver setup routines in printtup.c.  This makes for a clean distinction
between BeginCommand/EndCommand (once per command) and the tuple receiver
setup/teardown routines (once per ExecutorRun call), whereas the old code
was quite ad hoc.  Along the way, clean up the calling conventions for
ExecutorRun a little bit.

Tom Lane 56ee2ecba9 Restructure command-completion-report code so that there is just one
report for each received SQL command, regardless of rewriting activity.
Also ensure that this report comes from the 'original' command, not the

commands that have actions added by rules.  Fernando Nasser and Tom Lane.
