fdac8cf998 Check to ensure the number of primary key fields supplied does not
exceed the total number of non-dropped source table fields for
dblink_build_sql_*(). Addresses bug report from Rushabh Lathia.

Backpatch all the way to the 7.3 branch.

f4095b4c4b Implement dblink_get_notify().
Adds the ability to retrieve async notifications using dblink,
via the addition of the function dblink_get_notify(). Original patch
by Marcus Kempe, suggestions by Tom Lane and Alvaro Herrera, patch
review and adjustments by Joe Conway.

4334695b30 Add support for using SQL/MED compliant FOREIGN DATA WRAPPER, SERVER,
and USER MAPPING as method to supply dblink connect parameters. Per
mailing list and PGCon discussions.

2604359251 Improve hash_any() to use word-wide fetches when hashing suitably aligned
data.  This makes for a significant speedup at the cost that the results
now vary between little-endian and big-endian machines; which forces us
to add explicit ORDER BYs in a couple of regression tests to preserve
machine-independent comparison results.  Also, force initdb by bumping
catversion, since the contents of hash indexes will change (at least on
big-endian machines).

Kenneth Marshall and Tom Lane, based on work from Bob Jenkins.  This commit
does not adopt Bob's new faster mix() algorithm, however, since we still need
to convince ourselves that that doesn't degrade the quality of the hashing.

f96928fde9 Implement current_query(), that shows the currently executing query.
At the same time remove dblink/dblink_current_query() as it is no longer
necessary

919c9f6cce The original patch to disallow non-passworded connections to non-superusers
failed to cover all the ways in which a connection can be initiated in dblink.
Plug the remaining holes.  Also, disallow transient connections in functions
for which that feature makes no sense (because they are only sensible as
part of a sequence of operations on the same connection).  Joe Conway

30e2c42e00 Fix a few contrib regression test scripts that hadn't gotten the word
about best practice for including the module creation scripts: to wit
that you should suppress NOTICE messages.  This avoids creating
regression failures by adding or removing comment lines in the module
scripts.

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.

4e7d6f5349 Add a --dbname option to the pg_regress script, and use pl_regression
for testing PLs and contrib_regression for testing contrib, instead of
overwriting the core system's regression database as formerly done.

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.

d1824a5ccb Fix regression in dblink_disconnect() reported by Eduardo Stern:
persistent_conn was left dangling after a disconnect in the
unnamed connection case, causing a subsequent disconnect to
crash the backend.

f85f43dfb5 Backend support for autocommit removed, per recent discussions. The
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON.  Still TODO: provide some client-side autocommit
logic in libpq.

bfccacf3f8 Fix dblink regression test so that it works when repeated: don't
create a second database, just loop back to 'regression'.  Patch
from Joe Conway 10/22/02.

e5cf1a8a26 SET autocommit no longer needed in /contrib because pg_regress.sh does
it automatically now on regression session startup.

aa4c702eac Update /contrib for "autocommit TO 'on'".
Create objects in public schema.

Make spacing/capitalization consistent.

Remove transaction block use for object creation.

Remove unneeded function GRANTs.

cd7a3b6c0d Simplify handling of second database for dblink tests. 2002-09-14 22:00:59 +00:00
Tom Lane
d724c314da The attached adds GRANTs to PUBLIC for dblink functions, removes the
non-standard regression test, and adds standard installcheck regression test
support.

The test creates a second database (regression_slave) and drops it again, in
order to avoid the cheesy-ness of connecting back to the same database ;-)
