ad69bd052f Add mode where contrib installcheck runs each module in a separately named database.
Normally each module is tested in a database named contrib_regression,
which is dropped and recreated at the beginhning of each pg_regress run.
This new mode, enabled by adding USE_MODULE_DB=1 to the make command
line, runs most modules in a database with the module name embedded in
it.

This will make testing pg_upgrade on clusters with the contrib modules
a lot easier.

Second attempt at this, this time accomodating make versions older
than 3.82.

Still to be done: adapt to the MSVC build system.

Backpatch to 9.0, which is the earliest version it is reasonably
possible to test upgrading from.

c3bf3ea2b6 Remove configure-option-dependent test cases from dblink tests.
The HINTs generated for these error cases vary across builds.  We
could try to work around that, but the test cases aren't really useful
enough to justify taking any trouble.

Per buildfarm.

8255566f9d Create an improved FDW option validator function for contrib/dblink.
dblink now has its own validator function dblink_fdw_validator(), which is
better than the core function postgresql_fdw_validator() because it gets
the list of legal options from libpq instead of having a hard-wired list.

Make the dblink extension module provide a standard foreign data wrapper
dblink_fdw that encapsulates use of this validator, and recommend use of
that wrapper instead of making up wrappers on the fly.

Unfortunately, because ad-hoc wrappers *were* recommended practice
previously, it's not clear when we can get rid of postgresql_fdw_validator
without causing upgrade problems.  But this is a step in the right
direction.

c219d9b0a5 Split tuple struct defs from htup.h to htup_details.h
This reduces unnecessary exposure of other headers through htup.h, which
is very widely included by many files.

I have chosen to move the function prototypes to the new file as well,
because that means htup.h no longer needs to include tupdesc.h.  In
itself this doesn't have much effect in indirect inclusion of tupdesc.h
throughout the tree, because it's also required by execnodes.h; but it's
something to explore in the future, and it seemed best to do the htup.h
change now while I'm busy with it.

41b9c8452b Replace libpq's "row processor" API with a "single row" mode.
After taking awhile to digest the row-processor feature that was added to
libpq in commit 92785dac2e, we've concluded
it is over-complicated and too hard to use.  Leave the core infrastructure
changes in place (that is, there's still a row processor function inside
libpq), but remove the exposed API pieces, and instead provide a "single
row" mode switch that causes PQgetResult to return one row at a time in
separate PGresult objects.

This approach incurs more overhead than proper use of a row processor
callback would, since construction of a PGresult per row adds extra cycles.
However, it is far easier to use and harder to break.  The single-row mode
still affords applications the primary benefit that the row processor API
was meant to provide, namely not having to accumulate large result sets in
memory before processing them.  Preliminary testing suggests that we can
probably buy back most of the extra cycles by micro-optimizing construction
of the extra results, but that task will be left for another day.

6f922ef88e Improve efficiency of dblink by using libpq's new row processor API.
This patch provides a test case for libpq's row processor API.
contrib/dblink can deal with very large result sets by dumping them into
a tuplestore (which can spill to disk) --- but until now, the intermediate
storage of the query result in a PGresult meant memory bloat for any large
result.  Now we use a row processor to convert the data to tuple form and
dump it directly into the tuplestore.

A limitation is that this only works for plain dblink() queries, not
dblink_send_query() followed by dblink_get_result().  In the latter
case we don't know the desired tuple rowtype soon enough.  While hack
solutions to that are possible, a different user-level API would
probably be a better answer.

d843ed2116 Fix a couple of contrib/dblink bugs.
dblink_exec leaked temporary database connections if any error occurred
after connection setup, for example
	SELECT dblink_exec('...connect string...', 'select 1/0');
Add a PG_TRY block to ensure PQfinish gets done when it is needed.
(dblink_record_internal is on the hairy edge of needing similar treatment,
but seems not to be actively broken at the moment.)

Also, in 9.0 and up, only one of the three functions using tuplestore
return mode was properly checking that the query context would allow
a tuplestore result.

Noted while reviewing dblink patch.  Back-patch to all supported branches.

b75fbe9191 Fix dblink's failure to report correct connection name in error messages.
The DBLINK_GET_CONN and DBLINK_GET_NAMED_CONN macros did not set the
surrounding function's conname variable, causing errors to be incorrectly
reported as having occurred on the "unnamed" connection in some cases.
This bug was actually visible in two cases in the regression tests,
but apparently whoever added those cases wasn't paying attention.

Noted by Kyotaro Horiguchi, though this is different from his proposed
patch.

Back-patch to 8.4; 8.3 does not have the same type of error reporting
so the patch is not relevant.

458857cc9d Throw a useful error message if an extension script file is fed to psql.
We have seen one too many reports of people trying to use 9.1 extension
files in the old-fashioned way of sourcing them in psql.  Not only does
that usually not work (due to failure to substitute for MODULE_PATHNAME
and/or @extschema@), but if it did work they'd get a collection of loose
objects not an extension.  To prevent this, insert an \echo ... \quit
line that prints a suitable error message into each extension script file,
and teach commands/extension.c to ignore lines starting with \echo.
That should not only prevent any adverse consequences of loading a script
file the wrong way, but make it crystal clear to users that they need to
do it differently now.

Tom Lane, following an idea of Andrew Dunstan's.  Back-patch into 9.1
... there is not going to be much value in this if we wait till 9.2.

f8ebe3bcc5 Support "make check" in contrib
Added a new option --extra-install to pg_regress to arrange installing
the respective contrib directory into the temporary installation.
This is currently not yet supported for Windows MSVC builds.

Updated the .gitignore files for contrib modules to ignore the
leftovers of a temp-install check run.

Changed the exit status of "make check" in a pgxs build (which still
does nothing) to 0 from 1.

Added "make check" in contrib to top-level "make check-world".

029fac2264 Avoid use of CREATE OR REPLACE FUNCTION in extension installation files.
It was never terribly consistent to use OR REPLACE (because of the lack of
comparable functionality for data types, operators, etc), and
experimentation shows that it's now positively pernicious in the extension
world.  We really want a failure to occur if there are any conflicts, else
it's unclear what the extension-ownership state of the conflicted object
ought to be.  Most of the time, CREATE EXTENSION will fail anyway because
of conflicts on other object types, but an extension defining only
functions can succeed, with bad results.

629b3af27d Convert contrib modules to use the extension facility.
This isn't fully tested as yet, in particular I'm not sure that the
"foo--unpackaged--1.0.sql" scripts are OK.  But it's time to get some
buildfarm cycles on it.

sepgsql is not converted to an extension, mainly because it seems to
require a very nonstandard installation process.

c0989c67fa Change the interpretation of the primary_key_attnums parameter of
dblink_build_sql_insert() and related functions.  Now the column numbers
are treated as logical not physical column numbers.  This will provide saner
behavior in the presence of dropped columns; furthermore, if we ever get
around to allowing rearrangement of logical column ordering, the original
definition would become nearly untenable from a usability standpoint.
Per recent discussion of dblink's handling of dropped columns.
Not back-patched for fear of breaking existing applications.

6bbaa3148d Rearrange dblink's dblink_build_sql_insert() and related routines to open and
lock the target relation just once per SQL function call.  The original coding
obtained and released lock several times per call.  Aside from saving a
not-insignificant number of cycles, this eliminates possible race conditions
if someone tries to modify the relation's schema concurrently.  Also
centralize locking and permission-checking logic.

Problem noted while investigating a trouble report from Robert Voinea --- his
problem is still to be fixed, though.

e26c539e9f Wrap calls to SearchSysCache and related functions using macros.
The purpose of this change is to eliminate the need for every caller
of SearchSysCache, SearchSysCacheCopy, SearchSysCacheExists,
GetSysCacheOid, and SearchSysCacheList to know the maximum number
of allowable keys for a syscache entry (currently 4).  This will
make it far easier to increase the maximum number of keys in a
future release should we choose to do so, and it makes the code
shorter, too.

84d723b6ce Previous fix for temporary file management broke returning a set from
PL/pgSQL function within an exception handler. Make sure we use the right
resource owner when we create the tuplestore to hold returned tuples.

Simplify tuplestore API so that the caller doesn't need to be in the right
memory context when calling tuplestore_put* functions. tuplestore.c
automatically switches to the memory context used when the tuplestore was
created. Tuplesort was already modified like this earlier. This patch also
removes the now useless MemoryContextSwitch calls from callers.

1753337cf5 Improve psql's tabular display of wrapped-around data by inserting markers
in the formerly-always-blank columns just to left and right of the data.
Different marking is used for a line break caused by a newline in the data
than for a straight wraparound.  A newline break is signaled by a "+" in the
right margin column in ASCII mode, or a carriage return arrow in UNICODE mode.
Wraparound is signaled by a dot in the right margin as well as the following
left margin in ASCII mode, or an ellipsis symbol in the same places in UNICODE
mode.  "\pset linestyle old-ascii" is added to make the previous behavior
available if anyone really wants it.

In passing, this commit also cleans up a few regression test files that
had unintended spacing differences from the current actual output.
