how this ought to behave for multi-dimensional arrays.  Per discussion,
not having it at all seems better than having it with what might prove
to be the wrong behavior.  We can always add it later when we have consensus
on the correct behavior.

per bug #4752.  Fujii Masao

by my patch of 2007-01-28 to use per-subtransaction ExprContexts/EStates:
since we re-prepared any expression tree when the current subtransaction ID
changed, we'd accumulate more and more leaked expression state trees in the
outermost subtransaction if the same function was executed at multiple levels
of subtransaction nesting.  To fix, go back to the previous scheme where
there was only one EState per transaction for simple plpgsql expressions.
We really only need an ExprContext per subtransaction, not a whole EState,
so it's possible to keep prepared expression state trees in the one EState
throughout the transaction.  This should be more efficient as well as not
leaking memory for cases involving lots of subtransactions.

The added regression test is the case that inspired the 2007-01-28 patch in
the first place, just to make sure we didn't go backwards.  The current
memory leak complaint is unfortunately hard to test for in the regression
test framework, though manual testing shows it's fixed.

Although this is a pre-existing bug, I'm not back-patching because I'd like to
see this method get some field testing first.  Consider back-patching if it
gets through 8.4beta unscathed.

cstring from the output of \df.  Now that the default behavior is to
exclude all system functions, the de-cluttering rationale for this behavior
seems pretty weak; and it was always quite confusing/unhelpful if you were
actually looking for I/O functions.  (Not to mention if you were looking
for encoding converters or other cases that might take or return cstring.)

map_sql_value_to_xml_value() instead of directly through the data type output
function.  This is per SQL standard, and consistent with XMLELEMENT().

already did that on Windows, but it's needed on other platforms too when
LC_CTYPE=C. With other locales, we enforce (or trust) that the codeset of
the locale matches the server encoding so we don't need to bind it
explicitly. It should do no harm in that case either, but I don't have
full faith in the PG encoding -> OS codeset mapping table yet. Per recent
discussion on pgsql-hackers.

We should probably have a better way to do this (meaning
something not hardcoded) eventually, but this fixes the
problem for 8.4.

they won't be indexing off the ends of static arrays.

negligible --- what I'm interested in is making sure that if we have
second thoughts about the definition, we will not have to force a
post-beta initdb to change the implementation.

of discovery, rather than reverse order.  This doesn't matter functionally
(I suppose the previous coding dates from the time when lcons was markedly
cheaper than lappend).  However now that EXPLAIN is labeling subplans with
IDs that are based on order of creation, this may help produce a slightly
less surprising printout.
