3ca7eddbb7 Fix bug with multiple evaluation of tsearch2 compatibility trigger, trigger
data should be restored.
Backpatch only for 8.3 because previous versions haven't such layer.

1cfd9e8834 Fix executor/spi.h to follow our usual conventions for include files, ie,
not include postgres.h nor anything else it doesn't directly need.  Add
#includes to calling files as needed to compensate.  Per my proposal of
yesterday.

This should be noted as a source code change in the 8.4 release notes,
since it's likely to require changes in add-on modules.

ccdb6627ee Tweak guc.c to allow underscores in the names of custom variable classes,
and change auto_explain's custom GUC variables to be named auto_explain.xxx
not just explain.xxx.  Per discussion in connection with the
pg_stat_statements patch, it seems like a good idea to have the convention
that custom variable classes are named the same as their defining module.
Committing separately since this should happen regardless of what happens
with pg_stat_statements itself.

cf407f164e Refactor crosstab() to build and return a tuplestore instead of using
value-per-call mode.  This should be more efficient in normal usage,
but the real problem with the prior coding was that it returned with
a SPI call still active.  That could cause problems if execution was
interleaved with anything else that might use SPI.

3f936aacc0 Add a "LIKE = typename" clause to CREATE TYPE for base types. This allows
the basic representational details (typlen, typalign, typbyval, typstorage)
to be copied from an existing type rather than listed explicitly in the
CREATE TYPE command.  The immediate reason for this is to provide a simple
solution for add-on modules that want to define types represented as int8,
float4, or float8: as of 8.4 the appropriate PASSEDBYVALUE setting is
platform-specific and so it's hard for a SQL script to know what to do.

This patch fixes the contrib/isn breakage reported by Rushabh Lathia.

d141e7493b Fix old bug in contrib/sslinfo: X509_NAME_to_text freed the BIO_s_mem buffer
it was using too soon.  In a situation where pg_do_encoding_conversion is
a no-op, this led to garbage data returned.

In HEAD, also modify the code that's ensuring null termination to make it
a tad more obvious what's happening.

13fdd0e4d1 Add some more citext test cases, per David Wheeler. Also remove the
citext-to-and-from-xml tests, since those caused variation between
installations with or without libxml without really proving much.  Instead
repurpose citext_1.out as the expected results in glibc en_US (and probably
other) locales.

902d1cb35f Remove all uses of the deprecated functions heap_formtuple, heap_modifytuple,
and heap_deformtuple in favor of the newer functions heap_form_tuple et al
(which do the same things but use bool control flags instead of arbitrary
char values).  Eliminate the former duplicate coding of these functions,
reducing the deprecated functions to mere wrappers around the newer ones.
We can't get rid of them entirely because add-on modules probably still
contain many instances of the old coding style.

19c8dc839b Unite ReadBufferWithFork, ReadBufferWithStrategy, and ZeroOrReadBuffer
functions into one ReadBufferExtended function, that takes the strategy
and mode as argument. There's three modes, RBM_NORMAL which is the default
used by plain ReadBuffer(), RBM_ZERO, which replaces ZeroOrReadBuffer, and
a new mode RBM_ZERO_ON_ERROR, which allows callers to read corrupt pages
without throwing an error. The FSM needs the new mode to recover from
corrupt pages, which could happend if we crash after extending an FSM file,
and the new page is "torn".

Add fork number to some error messages in bufmgr.c, that still lacked it.

05bba3d176 Be more tense about not creating tuplestores with randomAccess = true unless
backwards scan could actually happen.  In particular, pass a flag to
materialize-mode SRFs that tells them whether they need to require random
access.  In passing, also suppress unneeded backward-scan overhead for a
Portal's holdStore tuplestore.  Per my proposal about reducing I/O costs for
tuplestores.

e3e3d2a789 Extend ExecMakeFunctionResult() to support set-returning functions that return
via a tuplestore instead of value-per-call.  Refactor a few things to reduce
ensuing code duplication with nodeFunctionscan.c.  This represents the
reasonably noncontroversial part of my proposed patch to switch SQL functions
over to returning tuplestores.  For the moment, SQL functions still do things
the old way.  However, this change enables PL SRFs to be called in targetlists
(observe changes in plperl regression results).

5f853c6556 Use fork names instead of numbers in the file names for additional
relation forks. While the file names are not visible to users, for those
that do peek into the data directory, it's nice to have more descriptive
names. Per Greg Stark's suggestion.

6736da5484 Make the blkno arguments bigints instead of int4s. A signed int4 is not
large enough for block numbers higher than 2^31. The old pre-FSM-rewrite
pg_freespacemap implementation got this right. While we're at it, remove
some unnecessary #includes.

15c121b3ed Rewrite the FSM. Instead of relying on a fixed-size shared memory segment, the
free space information is stored in a dedicated FSM relation fork, with each
relation (except for hash indexes; they don't use FSM).

This eliminates the max_fsm_relations and max_fsm_pages GUC options; remove any
trace of them from the backend, initdb, and documentation.

Rewrite contrib/pg_freespacemap to match the new FSM implementation. Also
introduce a new variant of the get_raw_page(regclass, int4, int4) function in
contrib/pageinspect that let's you to return pages from any relation fork, and
a new fsm_page_contents() function to inspect the new FSM pages.

cae7ad906a Fix dblink_connect() so that it verifies that a password is supplied in the
conninfo string *before* trying to connect to the remote server, not after.
As pointed out by Marko Kreen, in certain not-very-plausible situations
this could result in sending a password from the postgres user's .pgpass file,
or other places that non-superusers shouldn't have access to, to an
untrustworthy remote server.  The cleanest fix seems to be to expose libpq's
conninfo-string-parsing code so that dblink can check for a password option
without duplicating the parsing logic.

fbb2b69c8f Prevent memory leaks in our various bison parsers when an error occurs
during parsing.  Formerly the parser's stack was allocated with malloc
and so wouldn't be reclaimed; this patch makes it use palloc instead,
so that flushing the current context will reclaim the memory.  Per
Marko Kreen.

6152de97d3 Minor patch on pgbench
1. -i option should run vacuum analyze only on pgbench tables, not *all*
tables in database.

2. pre-run cleanup step was DELETE FROM HISTORY then VACUUM HISTORY.
This is just a slow version of TRUNCATE HISTORY.

c8572986ad Allow I/O conversion casts to be applied to or from any type that is a member
of the STRING type category, thereby opening up the mechanism for user-defined
types.  This is mainly for the benefit of citext, though; there aren't likely
to be a lot of types that are all general-purpose character strings.
Per discussion with David Wheeler.

42be2c790f Adjust citext to make use of the new ability to declare its type category:
by putting it into the standard string category, we cause casts from citext
to text to be recognized as "preferred" casts.  This eliminates the need
for creation of alias functions and operators that only serve to prevent
ambiguous-function errors; get rid of the ones that were in the original
commit.
