Tom Lane 7b970bc1bc Use aclcheck_error() in place of ad-hoc permissions complaints. 2002-07-29 23:44:44 +00:00
Tom Lane ea4686e3e1 Implement CREATE/DROP OPERATOR CLASS. Work still remains: need more
documentation (xindex.sgml should be rewritten), need to teach pg_dump
about it, need to update contrib modules that currently build pg_opclass
entries by hand.  Original patch by Bill Studenmund, grammar adjustments
and general update for 7.3 by Tom Lane.

Tom Lane a28375140c Fix minor coding error: don't ReleaseSysCache until after last use of
cache entry.

Peter Eisentraut 43515ba3f8 Remove _deadcode. 2002-07-24 19:16:43 +00:00
Peter Eisentraut 739adf32ee Remove unused system table columns:
pg_language.lancompiler
pg_operator.oprprec
pg_operator.oprisleft
pg_proc.proimplicit
pg_proc.probyte_pct
pg_proc.properbyte_cpu
pg_proc.propercall_cpu
pg_proc.prooutin_ratio
pg_shadow.usetrace
pg_type.typprtlen
pg_type.typreceive
pg_type.typsend

Attempts to use the obsoleted attributes of pg_operator or pg_proc
in the CREATE commands will be greeted by a warning.  For pg_type,
there is no warning (yet) because pg_dump scripts still contain these
attributes.

Also remove new but already obsolete spellings
isVolatile, isStable, isImmutable in WITH clause.  (Use new syntax
instead.)

Peter Eisentraut e9c013f4bd Add unique index on pg_cast.oid, and document pg_cast table. 2002-07-22 20:23:19 +00:00
Tom Lane b70b78656b Tweak CreateTrigger() so that the OID used in the name of an
RI_ConstraintTrigger is the same OID assigned to the pg_trigger row.
This reduces consumption of OIDs and may ease debugging.

Bruce Momjian 63cfc6a8e8 Fix problems caused by code drift of API for without-oids. 2002-07-20 06:17:43 +00:00

The July 9th Table Function API patch mentioned above is now in CVS, so
here is an updated version of the guc patch which should apply cleanly
against CVS tip.

Bruce Momjian dcbacde2e3 Patch problems caused by code drift since OID patch creation. 2002-07-20 05:37:45 +00:00
Bruce Momjian b0f5086e41 oid is needed, it is added at the end of the struct (after the null
bitmap, if present).

Per Tom Lane's suggestion the information whether a tuple has an oid
or not is carried in the tuple descriptor.  For debugging reasons
tdhasoid is of type char, not bool.  There are predefined values for
WITHOID, WITHOUTOID and UNDEFOID.

This patch has been generated against a cvs snapshot from last week
and I don't expect it to apply cleanly to current sources.  While I
post it here for public review, I'm working on a new version against a
current snapshot.  (There's been heavy activity recently; hope to
catch up some day ...)

This is a long patch;  if it is too hard to swallow, I can provide it
in smaller pieces:

Part 1:  Accessor macros
Part 2:  tdhasoid in TupDesc
Part 3:  Regression test
Part 4:  Parameter withoid to heap_addheader
Part 5:  Eliminate t_oid from HeapTupleHeader

Part 2 is the most hairy part because of changes in the executor and
even in the parser;  the other parts are straightforward.

Up to part 4 the patched postmaster stays binary compatible to
databases created with an unpatched version.  Part 5 is small (100
lines) and finally breaks compatibility.

Bruce Momjian e77054e029 This patch fixes a regression caused by my recent changes to heap
tuple header.  The fix is based on the thought that HEAP_MOVED_IN is
not needed any more as soon as HEAP_XMIN_COMMITTED has been set.  So
in tqual.c and vacuum.c the HEAP_MOVED bits are cleared when
HEAP_XMIN_COMMITTED is set.

Vacuum robustness is enhanced by rearranging ifs, so that we have a
chance to elog(ERROR, ...) before an assertion fails.

A new regression test is included.

Peter Eisentraut 97377048b4 pg_cast table, and standards-compliant CREATE/DROP CAST commands, plus
extension to create binary compatible casts.  Includes dependency tracking
as well.

pg_proc.proimplicit is now defunct, but will be removed in a separate
commit.

pg_dump provides a migration path from the previous scheme to declare
casts.  Dumping binary compatible casts is currently impossible, though.

Tom Lane 11333426f1 Implement DROP SCHEMA. It lacks support for dropping conversions and
operator classes, both of which are schema-local and so should really
be droppable.
2002-07-18 16:47:26 +00:00
Bruce Momjian a90db34b54 The attached patch (against HEAD) implements
COPY x (a,d,c,b) from stdin;
  COPY x (a,c) to stdout;

as well as the corresponding changes to pg_dump to use the new
functionality.  This functionality is not available when using
the BINARY option.  If a column is not specified in the COPY FROM
statement, its default values will be used.

In addition to this functionality, I tweaked a couple of the
error messages emitted by the new COPY <options> checks.

Tatsuo Ishii eb335a034b I have committed many support files for CREATE CONVERSION. Default
conversion procs and conversions are added in initdb. Currently
supported conversions are:

UTF-8(UNICODE) <--> SQL_ASCII, ISO-8859-1 to 16, EUC_JP, EUC_KR,
		    EUC_CN, EUC_TW, SJIS, BIG5, GBK, GB18030, UHC,
		    JOHAB, TCVN

EUC_JP <--> SJIS
EUC_TW <--> BIG5
MULE_INTERNAL <--> EUC_JP, SJIS, EUC_TW, BIG5

Note that initial contents of pg_conversion system catalog are created
in the initdb process. So doing initdb required is ideal, it's
possible to add them to your databases by hand, however. To accomplish
this:

psql -f your_postgresql_install_path/share/conversion_create.sql your_database

So I did not bump up the version in cataversion.h.

TODO:
Add more conversion procs
Add [CASCADE|RESTRICT] to DROP CONVERSION
Add tuples to pg_depend
Add regression tests
Write docs
Add SQL99 CONVERT command?

Tom Lane 5af19e4227 Add more dependency insertions --- this completes the basic pg_depend
functionality.  Of note: dropping a table that has a SERIAL column
defined now drops the associated sequence automatically.
2002-07-16 22:12:20 +00:00
Tom Lane 30ec31604d Add code to extract dependencies from an expression tree, and use it
to build dependencies for rules, constraint expressions, and default
expressions.  Repair some problems in the original design of
recursiveDeletion() exposed by more complex dependency sets.  Fix
regression tests that were deleting things in illegal sequences.
2002-07-16 05:53:34 +00:00
Tom Lane 7bd631bfa4 Use the dependency mechanism to manage column defaults. We need this
so that dependencies in default expressions (on operators, functions,
etc) can be expressed properly.
2002-07-15 16:33:32 +00:00
Tom Lane d5fa19c6ee Add COMMENT ON CONSTRAINT facility (from Rod Taylor's pg_constraint patch).
Fix comment.c to not depend on parser token values, per discussion awhile
back.
2002-07-14 23:38:13 +00:00
Tom Lane 7c6df91dda Second phase of committing Rod Taylor's pg_depend/pg_constraint patch.
pg_relcheck is gone; CHECK, UNIQUE, PRIMARY KEY, and FOREIGN KEY
constraints all have real live entries in pg_constraint.  pg_depend
exists, and RESTRICT/CASCADE options work on most kinds of DROP;
however, pg_depend is not yet very well populated with dependencies.
(Most of the ones that are present at this point just replace formerly
hardwired associations, such as the implicit drop of a relation's pg_type
entry when the relation is dropped.)  Need to add more logic to create
dependency entries, improve pg_dump to dump constraints in place of
indexes and triggers, and add some regression tests.
2002-07-12 18:43:19 +00:00
Tatsuo Ishii fcc962566a Add new CREATE CONVERSION/DROP CONVERSION command.
This is the first cut toward CREATE CONVERSION/DROP CONVERSION implementaion.
The commands can now add/remove tuples to the new pg_conversion system
catalog, but that's all. Still need work to make them actually working.
Documentations, regression tests also need work.
2002-07-11 07:39:28 +00:00
Bruce Momjian 1666970275 I've fixed up the way domain constraints (not null and type length)
are managed as per request.

Moved from merging with table attributes to applying themselves during
coerce_type() and coerce_type_typmod.

Regression tests altered to test the cast() scenarios.

2002-07-06 20:16:36 +00:00
Tom Lane 131f801d37 First phase of applying Rod Taylor's pg_depend patch. This just adds
RESTRICT/CASCADE syntax to the DROP commands that need it, and propagates
the behavioral option through the parser to the routines that execute
drops.  Doesn't do anything useful yet, but I figured I'd commit these
changes so I could get out of the parser area while working on the rest.

Bruce Momjian 3c35face41 This patch wraps all accesses to t_xmin, t_cmin, t_xmax, and t_cmax in
HeapTupleHeaderData in setter and getter macros called
HeapTupleHeaderGetXmin, HeapTupleHeaderSetXmin etc.

It also introduces a "virtual" field xvac by defining
HeapTupleHeaderGetXvac and HeapTupleHeaderSetXvac.  Xvac is used by
VACUUM, in fact it is stored in t_cmin.

Tom Lane 29737d83d9 AlterDatabaseSet() forgot to update the indexes on pg_database. 2002-05-25 16:30:59 +00:00
Tom Lane 3f4d488022 Mark index entries "killed" when they are no longer visible to any
transaction, so as to avoid returning them out of the index AM.  Saves
repeated heap_fetch operations on frequently-updated rows.  Also detect
queries on unique keys (equality to all columns of a unique index), and
don't bother continuing scan once we have found first match.

Killing is implemented in the btree and hash AMs, but not yet in rtree
or gist, because there isn't an equally convenient place to do it in
those AMs (the outer amgetnext routine can't do it without re-pinning
the index page).

Did some small cleanup on APIs of HeapTupleSatisfies, heap_fetch, and
index_insert to make this a little easier.
2002-05-24 18:57:57 +00:00
Tom Lane a2597ef179 Modify sequence state storage to eliminate dangling-pointer problem
exemplified by bug #671.  Moving the storage to relcache turned out to
be a bad idea because relcache might decide to discard the info.  Instead,
open and close the relcache entry on each sequence operation, and use
a record of the current XID to discover whether we already hold
AccessShareLock on the sequence.
2002-05-22 21:40:55 +00:00
Peter Eisentraut d60f10b0e7 Add optional "validator" function to languages that can validate the
function body (and other properties) as a function in the language
is created.  This generalizes ad hoc code that already existed for
the built-in languages.

The validation now happens after the pg_proc tuple of the new function
is created, so it is possible to define recursive SQL functions.

Add some regression test cases that cover bogus function definition
attempts.
2002-05-22 17:21:02 +00:00
Tom Lane 6c6f395a8a Since COPY fires triggers, it seems like a good idea for it to use
a frozen (copied) snapshot too.  Move execMain's snapshot copying code
out into a subroutine in case we find other places that need it.
2002-05-21 22:59:01 +00:00
Tom Lane 959e61e917 Remove global variable scanCommandId in favor of storing a command ID
in snapshots, per my proposal of a few days ago.  Also, tweak heapam.c
routines (heap_insert, heap_update, heap_delete, heap_mark4update) to
be passed the command ID to use, instead of doing GetCurrentCommandID.
For catalog updates they'll still get passed current command ID, but
for updates generated from the main executor they'll get passed the
command ID saved in the snapshot the query is using.  This should fix
some corner cases associated with functions and triggers that advance
current command ID while an outer query is still in progress.

Tom Lane 44fbe20d62 Restructure indexscan API (index_beginscan, index_getnext) per
yesterday's proposal to pghackers.  Also remove unnecessary parameters
to heap_beginscan, heap_rescan.  I modified pg_proc.h to reflect the
new numbers of parameters for the AM interface routines, but did not
force an initdb because nothing actually looks at those fields.

path by folding special cases into the main list.
