as this seems only likely to create headaches for module developers.  Put
the macro in the pre-existing fmgr.h file instead.  Avoid being too cute
about how many fields we can cram into a word, and avoid trying to fetch
from a library we've already unlinked.
Along the way, it occurred to me that the magic block really ought to be
'const' so it can be stored in the program text area.  Do the same for
the existing data blocks for PG_FUNCTION_INFO_V1 functions.

across multiple loops, get rid of the shaky assumption that exactly one
tuple is returned per node iteration.

This is just the minimal necessary change; we might want to adopt
later PPPort output instead.

It now only checks four things:

Major version number (7.4 or 8.1 for example)
NAMEDATALEN
FUNC_MAX_ARGS
INDEX_MAX_KEYS

The three constants were chosen because:

1. We document them in the config page in the docs
2. We mark them as changable in pg_config_manual.h
3. Changing any of these will break some of the more popular modules:

FUNC_MAX_ARGS changes fmgr interface, every module uses this NAMEDATALEN
changes syscache interface, every PL as well as tsearch uses this
INDEX_MAX_KEYS breaks tsearch and anything using GiST.

Add dynamic record inspection to PL/PgSQL, useful for generic triggers:

Delay write of pg_stats file to once every five minutes, during
shutdown, or when requested by a backend:

It changes so the file is only written once every 5 minutes (changeable
of course, I just picked something) instead of once every half second.
It's still written when the stats collector shuts down, just as before.
And it is now also written on backend request. A backend requests a
rewrite by simply sending a special stats message. It operates on the
assumption that the backends aren't actually going to read the
statistics file very often, compared to how frequent it's written today.

Make plperl's $_TD trigger data a global rather than a lexical variable,
with a fresh local value for each invocation, to avoid unexpected sharing
violations. Per recent -hackers discussion.

If user picksplit on n-th column generate equals
left and right unions then it calls picksplit on n+1-th
column.

and standard_conforming_strings; likewise for the other client programs
that need it.  As per previous discussion, a pg_dump dump now conforms
to the standard_conforming_strings setting of the source database.
We don't use E'' syntax in the dump, thereby improving portability of
the SQL.  I added a SET escape_strings_warning = off command to keep
the dumps from getting a lot of back-chatter from that.

Zero out the pointer fields of PGresult so that these mistakes are more
easily catched, per discussion.

this particular change breaks the build on Windows, so fix it now.

JOIN, which I removed in a recent fit of over-optimism that we wouldn't
have any future use for it.  Now it's needed to support disambiguating
WITH CHECK OPTION from WITH TIME ZONE.  As proof of concept, add stub
grammar productions for WITH CHECK OPTION.

Looks like the new plpython regression test fails on older pythons. See if this works.

'off'. This allows pg_dump output with standard_conforming_strings =
'on' to generate proper strings that can be loaded into other databases
without the backslash doubling we typically do.  I have added the
dumping of the standard_conforming_strings value to pg_dump.

I also added standard backslash handling for plpgsql.

per-call overhead is quite significant, at least on Linux: whatever
it's doing is more than just shoving the bytes into a buffer.  Buffering
the data so we can call fwrite() just once per row seems to be a win.

Add table_name and table_schema to plpython trigger data, plus docs and regression test.

Add table_name and table_schema to plperl trigger data. relname is
kept but now deprecated. Patch from Adam Sjøgren. Add regression test to
show plperl trigger data (Andrew).
TBD: apply similar changes to plpgsql, plpython and pltcl.
