Also fix missing SET_YYLLOC() in the {dolqfailed} production that I suppose
this was based on.  The latter is a pre-existing bug, but the only effect
is to misplace the error cursor by one token, so probably not worth
backpatching.

If a currently running item needs an exclusive lock on any item that the candidate items needs
any sort of lock on, or vice versa, then the candidate item is not allowed to run now, and
must wait till later.

tablespaces in an order that has some chance of working.
Per a complaint from Kevin Bailey.

This is a pre-existing bug, but given the lack of prior complaints I'm
not sure it's worth back-patching.  In most cases failure of the DROP
commands wouldn't be that important anyway.

In passing, fix syntax errors in dumpCreateDB()'s queries for old servers;
these were apparently introduced in recent binary_upgrade patch.

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.)
