don't cause confusion with the built-in anyarray versions of those operators.
Adjust the module's index opclasses to support the built-in operators in place
of the private ones.
The private implementations are still available under their historical
names @ and ~, so no functionality is lost. Some quick testing suggests
that they offer no real benefit over the core operators, however.
Per a complaint from Rusty Conover.
temporary tables of other sessions; that is unsafe because of the way our
buffer management works. Per report from Stuart Bishop.
This is redundant with the bufmgr.c checks in HEAD, but not at all redundant
in the back branches.
method to pass extra data to the consistent() and comparePartial() methods.
This is the core infrastructure needed to support the soon-to-appear
contrib/btree_gin module. The APIs are still upward compatible with the
definitions used in 8.3 and before, although *not* with the previous 8.4devel
function definitions.
catversion bump for changes in pg_proc entries (although these are just
cosmetic, since GIN doesn't actually look at the function signature before
calling it...)

not global variables of anonymous enum types. This didn't actually hurt
much because most linkers will just merge the duplicated definitions ...
but some will complain. Per bug #4731 from Ceriel Jacobs.
Backpatch to 8.1 --- the declarations don't exist before that.
reinstalling the default signal handler doesn't work as it is on Windows.
Presumably core dumps on SIGQUIT are not a problem on Windows, so rather
than figure out what header files or other changes are required to make it
work, just don't bother.
postmaster uses for immediate shutdown. Trap SIGUSR1 as the preferred
signal for that.
Per report by Fujii Masao and subsequent discussion on -hackers.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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).
pointers. This is only a whitespace change, which ought to be ignored
by regression testing, but for some reason buildfarm member spoonbill
doesn't like it.
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.
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.
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.
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.
