failing to find pg_hba.conf should be a fatal error anyway, so I
increased the priority of the elog() from LOG to FATAL and refactored
the code a little bit.

in the planned representation of a subplan at all any more, only SubPlan.
This means subselect.c doesn't scribble on its input anymore, which seems
like a good thing; and there are no longer three different possible
interpretations of a SubLink. Simplify node naming and improve comments
in primnodes.h. No change to stored rules, though.
produce which output in the geometry test, even with the problem narrowed
down to only whether they print minus zero or not. Instead, use
pg_regress' locale-variant mechanism to automatically consider the test
to pass if it matches either supplied comparison file. geometry_1.out
replaces the former geometry-positive-zeros.out.
execution state trees, and ExecEvalExpr takes an expression state tree
not an expression plan tree. The plan tree is now read-only as far as
the executor is concerned. Next step is to begin actually exploiting
this property.
completion. Note that it's based on 7.3 tarball, not CVS HEAD, or 7.3rel
branch. Damn, looking at CVS, this will patch into 7.3rel (just tested,
it does) probably collide with Rod Taylor's patch adding ALTER TRIGGER
stuff. O.K, second patch attached against HEAD - not tested, hand
merged.

* Add schema, cast, and conversion backslash commands to psql
I had to create a new publically available function,
pg_conversion_is_visible, as it seemed to be missing from the catalogs.
This required me to do no small amount of hacking around in namespace.c
I have updated the \? help and sgml docs.
\dc - list conversions [PATTERN]
\dC - list casts
\dn list schemas
I didn't support patterns with casts as there's nothing obvious to match
against.
Catalog version incremented --- initdb required.

make VALUE a non-reserved word again, use less invasive method of passing
ConstraintTestValue into transformExpr, fix problems with nested constraint
testing, do correct thing with NULL result from a constraint expression,
remove memory leak. Domain checks still need much more work if we are going
to allow ALTER DOMAIN, however.
so that all executable expression nodes inherit from a common supertype
Expr. This is somewhat of an exercise in code purity rather than any
real functional advance, but getting rid of the extra Oper or Func node
formerly used in each operator or function call should provide at least
a little space and speed improvement.
initdb forced by changes in stored-rules representation.
documentation and regression test mods. It seemed small and unobtrusive enough
to not require a specific proposal on the hackers list -- but if not, let me
know and I'll make a pitch. Otherwise, if there are no objections please apply.

postgresql version 7.3, but yea... this patch adds full IPv6
support to postgres. I've tested it out on 7.2.3 and has
been running perfectly stable.

=====================
I suggested an improvement of the inserttable in the PyGreSQL interface
already in January, but seemingly it was never implemented. I was told this
is the right place to get patches in for PyGreSQL, so I'm reposting my patch
here.
I consider the inserttable methode essential in populating the database
because of its benefits in performance compared to insert, so I think this
patch is quite essential. The attachment is an improved version of the
corresponding pg_inserttable function in pgmodule.c, which fixes the
following problems:
* The function raised exceptions because PyList_GetItem was used beyond the
size of the list. This was checked by comparing the result with NULL, but
the exception was not cleaned up, which could result in mysterious errors in
the following Python code. Instead of clearing the exception using
PyErr_Clear or something like that, I avoided throwing the exception at all
by at first requesting the size of the list. Using this opportunity, I also
checked the uniformity of the size of the rows passed in the lists/tuples.
The function also accepts (and silently ignores) empty lists and sublists.
* Python "None" values are now accepted and properly converted to PostgreSQL
NULL values
* The function now generates an error message in case of a line buffer
overflow
* It copes with tabulators, newlines and backslashes in strings now
* Rewrote the buffer filling code which should now run faster by avoiding
unnecessary string copy operations forth and back

cleaning up locale names and nothing else. Since all the locale names
are in plain ASCII I think it will be safe to use ASCII-only lower-case
conversion.
