056eb1412c When a cursor is opened using dblink_open, only start a transaction
if there isn't one already open. Upon dblink_close, only commit
the open transaction if it was started by dblink_open, and only
then when all cursors opened by dblink_open are closed. The transaction
accounting is done individually for all named connections, plus
the persistent unnamed connection.

978129f28e Document get_call_result_type() and friends; mark TypeGetTupleDesc()
and RelationNameGetTupleDesc() as deprecated; remove uses of the
latter in the contrib library.  Along the way, clean up crosstab()
code and documentation a little.

e92a88272e Modify hash_search() API to prevent future occurrences of the error
spotted by Qingqing Zhou.  The HASH_ENTER action now automatically
fails with elog(ERROR) on out-of-memory --- which incidentally lets
us eliminate duplicate error checks in quite a bunch of places.  If
you really need the old return-NULL-on-out-of-memory behavior, you
can ask for HASH_ENTER_NULL.  But there is now an Assert in that path
checking that you aren't hoping to get that behavior in a palloc-based
hash table.
Along the way, remove the old HASH_FIND_SAVE/HASH_REMOVE_SAVED actions,
which were not being used anywhere anymore, and were surely too ugly
and unsafe to want to see revived again.

162bd08b3f Completion of project to use fixed OIDs for all system catalogs and
indexes.  Replace all heap_openr and index_openr calls by heap_open
and index_open.  Remove runtime lookups of catalog OID numbers in
various places.  Remove relcache's support for looking up system
catalogs by name.  Bulky but mostly very boring patch ...

70c9763d48 Convert oidvector and int2vector into variable-length arrays. This
change saves a great deal of space in pg_proc and its primary index,
and it eliminates the former requirement that INDEX_MAX_KEYS and
FUNC_MAX_ARGS have the same value.  INDEX_MAX_KEYS is still embedded
in the on-disk representation (because it affects index tuple header
size), but FUNC_MAX_ARGS is not.  I believe it would now be possible
to increase FUNC_MAX_ARGS at little cost, but haven't experimented yet.
There are still a lot of vestigial references to FUNC_MAX_ARGS, which
I will clean up in a separate pass.  However, getting rid of it
altogether would require changing the FunctionCallInfoData struct,
and I'm not sure I want to buy into that.

fe2bfa6332 This makes dblink pass its installcheck test on platforms where
snprintf(data, len, %s, NULL) crash.

The code was trying to find a connection by name when it already had an
unnamed connection and did not have a name to search with.

8ec05b28b7 Modify hash_create() to elog(ERROR) if an error occurs, rather than
returning a NULL pointer (some callers remembered to check the return
value, but some did not -- it is safer to just bail out).

Also, cleanup pgstat.c to use elog(ERROR) rather than elog(LOG) followed
by exit().

f7332e88b9 Remove duplicate PQclear(res) operations leading to double free() and
subsequent core dump.  It looks like at one time DBLINK_RES_ERROR_AS_NOTICE
didn't include a PQclear, but now it does and so these other ones are
duplicate.

375369acd1 Replace TupleTableSlot convention for whole-row variables and function
results with tuples as ordinary varlena Datums.  This commit does not
in itself do much for us, except eliminate the horrid memory leak
associated with evaluation of whole-row variables.  However, it lays the
groundwork for allowing composite types as table columns, and perhaps
some other useful features as well.  Per my proposal of a few days ago.

6a1e2b3c28 Added new versions of dblink, dblink_exec, dblink_open, dblink_close,
and, dblink_fetch -- allows ERROR on remote side of connection to
throw NOTICE locally instead of ERROR. Also removed documentation for
previously deprecated, now removed, functions.

3cd8411826 When returning type "record", replace use of pgresultGetTupleDesc
with ReturnSetInfo->expectedDesc. This allows custom datatypes
(e.g. from tsearch2) to be returned at runtime. Previous behavior
depended on the type oid to match between the remote and local
database, which obviously doesn't work well for custom types.
Per report from Mark Gibson.

fa5c8a055a Cross-data-type comparisons are now indexable by btrees, pursuant to my
pghackers proposal of 8-Nov.  All the existing cross-type comparison
operators (int2/int4/int8 and float4/float8) have appropriate support.
The original proposal of storing the right-hand-side datatype as part of
the primary key for pg_amop and pg_amproc got modified a bit in the event;
it is easier to store zero as the 'default' case and only store a nonzero
when the operator is actually cross-type.  Along the way, remove the
long-since-defunct bigbox_ops operator class.

c1d62bfd00 Add operator strategy and comparison-value datatype fields to ScanKey.
Remove the 'strategy map' code, which was a large amount of mechanism
that no longer had any use except reverse-mapping from procedure OID to
strategy number.  Passing the strategy number to the index AM in the
first place is simpler and faster.
This is a preliminary step in planned support for cross-datatype index
operations.  I'm committing it now since the ScanKeyEntryInitialize()
API change touches quite a lot of files, and I want to commit those
changes before the tree drifts under me.

fc8d970cbc Replace functional-index facility with expressional indexes. Any column
of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects).  This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up.  Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.

7b8eb0b4f1 Attached is a fairly sizeable update to contrib/dblink. I'd love to get
review/feedback if anyone is interested and can spend the time. But I'd
also love to get this committed and address changes as incremental
patches ;-), so if there are no objections, please apply.

Below I'll give a synopsis of the changes. More detailed descriptions
are now in a new doc directory under contrib/dblink. There is also a new

dblink.test.sql file which will give a pretty good overview of the
functions and their use.

5cabcfccce Modify array operations to include array's element type OID in the
array header, and to compute sizing and alignment of array elements
the same way normal tuple access operations do --- viz, using the
tupmacs.h macros att_addlength and att_align.  This makes the world
safe for arrays of cstrings or intervals, and should make it much
easier to write array-type-polymorphic functions; as examples see
the cleanups of array_out and contrib/array_iterator.  By Joe Conway
and Tom Lane.

38bb77a5d1 ALTER TABLE DROP COLUMN works. Patch by Christopher Kings-Lynne,
code review by Tom Lane.  Remaining issues: functions that take or
return tuple types are likely to break if one drops (or adds!)
a column in the table defining the type.  Need to think about what
to do here.

Along the way: some code review for recent COPY changes; mark system
columns attnotnull = true where appropriate, per discussion a month ago.

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.

3bf6b8f06a Attached is an update to contrib/dblink. Please apply if there are no
objections.

Major changes:
   - removed cursor wrap around input sql to allow for remote
     execution of INSERT/UPDATE/DELETE
   - dblink now returns a resource id instead of a real pointer
   - added several utility functions

I'm still hoping to add explicit cursor open/fetch/close support before
7.3 is released, but I need a bit more time on that.

On a somewhat unrelated topic, I never got any feedback on the
unknownin/out patch and the mb_substring patch. Is there anything else I
need to do to get those applied?
