each tuple, as per my proposal of several days ago.  Also, clean up
sort memory management by keeping all working data in a separate memory
context, and refine the handling of low-memory conditions.

Kirkwood, minor improvements by Neil Conway. The regression tests have
been updated and the catversion has been bumped.

- "Add ON COMMIT capability to CREATE TABLE AS ... SELECT" is done

- "Allow PREPARE to automatically determine parameter types" is done

- "Clean up compiler warnings (especially with gcc version 4)" is done:
  AFAIK there are no remaining gcc4 compiler warnings to be fixed.

- Creating rules to do view updates is *not* an easy TODO item

the script is not executable as UCS_to_most.pl is in CVS.  It also won't
pick up any custom setting of the perl version/location to use.  This
patch calls perl scripts like $(PERL) $(srcdir)/script.pl.

Make restricted_exec feature for Windows more robust by using the environment
to pass the flag instead of the command line - some implementations of
getopt fail if getopt arguments are present after non-getopt arguments.

make initdb -U username work as advertised; back out bogus patch at rev 1.42
and supply real fix for problem it tried to address.

possible ScanDirection alternatives rather than magic numbers
(-1, 0, 1).  Also, use the ScanDirection macros in a few places
rather than directly checking whether `dir == ForwardScanDirection'
and the like. Per patch from James William Pye. His patch also
changed ScanDirection to be a "char" rather than an enum, which
I haven't applied.

by decompiling the typdefaultbin expression, not just printing the typdefault
text which may be out-of-date or assume the wrong schema search path.  (It's
the same hazard as for adbin vs adsrc in column defaults.)  The catalogs.sgml
spec for pg_type implies that the correct procedure is to look to
typdefaultbin first and consider typdefault only if typdefaultbin is NULL.
I made dumping of both domains and base types do that, even though in the
current backend code typdefaultbin is always correct for domains and
typdefault for base types --- might as well try to future-proof it a little.
Per bug report from Alexander Galler.

as Tru64's.  Per previous discussion.

in leaking memory when invoking a PL/Python procedure that raises an
exception. Unfortunately this still leaks memory, but at least the
largest leak has been plugged.

This patch also fixes a reference counting mistake in PLy_modify_tuple()
for 8.0, 8.1 and HEAD: we don't actually own a reference to `platt', so
we shouldn't Py_DECREF() it.

allocates the control data.  The per-tape buffers are allocated only
on first use.  This saves memory in situations where tuplesort.c
overestimates the number of tapes needed (ie, there are fewer runs
than tapes).  Also, this makes legitimate the coding in inittapes()
that includes tape buffer space in the maximum-memory calculation:
when inittapes runs, we've already expended the whole allowed memory
on tuple storage, and so we'd better not allocate all the tape buffers
until we've flushed some tuples out of memory.

with fixed merge order (fixed number of "tapes") was based on obsolete
assumptions, namely that tape drives are expensive.  Since our "tapes"
are really just a couple of buffers, we can have a lot of them given
adequate workspace.  This allows reduction of the number of merge passes
with consequent savings of I/O during large sorts.

required by the SQL standard, and TABLESPACE is useful functionality.
Patch from Kris Jurka, minor editorialization by Neil Conway.

pgcrypto crypt()/md5 and hmac() leak memory when compiled against
OpenSSL as openssl.c digest ->reset will do two DigestInit calls
against a context.  This happened to work with OpenSSL 0.9.6
but not with 0.9.7+.

Reason for the messy code was that I tried to avoid creating
wrapper structure to transport algorithm info and tried to use
OpenSSL context for it.  The fix is to create wrapper structure.

It also uses newer digest API to avoid memory allocations
on reset with newer OpenSSLs.

Thanks to Daniel Blaisdell for reporting it.

up a bunch of the support utilities.

In src/backend/utils/mb/Unicode remove nearly duplicate copies of the
UCS_to_XXX perl script and replace with one version to handle all generic
files.  Update the Makefile so that it knows about all the map files.
This produces a slight difference in some of the map files, using a
uniform naming convention and not mapping the null character.

In src/backend/utils/mb/conversion_procs create a master utf8<->win
codepage function like the ISO 8859 versions instead of having a separate
handler for each conversion.

There is an externally visible change in the name of the win1258 to utf8
conversion.  According to the documentation notes, it was named
incorrectly and this changes it to a standard name.

Running the Unicode mapping perl scripts has shown some additional mapping
changes in koi8r and iso8859-7.

this a test for specific AIX versions, but I don't know which ones need it.

we are not holding a buffer content lock; where it was, InterruptHoldoffCount
is positive and so we'd not respond to cancel signals as intended.  Also
add missing vacuum_delay_point() call in btvacuumcleanup.  This should fix
complaint from Evgeny Gridasov about failure to respond to SIGINT/SIGTERM
in a timely fashion (bug #2257).
