FOR loops are giving weird syntax errors. Restructure parsing of FOR
loops so that the integer-loop-vs-query-loop decision is driven off
the presence of '..' between IN and LOOP, rather than the presence
of a matching record/row variable name. Hopefully this will make the
behavior a bit more transparent.
better SQL compliance in this area, per recent discussion. Mark related
operators as commutators where possible. (The system doesn't actually care
about commutator marking for operators not returning boolean, at the moment,
but this seems forward-thinking and besides it made it easier to verify
that we hadn't missed any.)
Also, remove interval-minus-time and interval-minus-timetz operators.
I'm not sure how these got in, but they are nonstandard and had very
obviously broken behavior. (minus is not commutative in anyone's book.)
I doubt anyone had ever used 'em, because we'd surely have gotten a bug
report about it if so.
From an idea of Bruce, the attached patch implements the function
pg_tablespace_databases(oid) RETURNS SETOF oid
which delivers as set of database oids having objects in the selected
tablespace, enabling an admin to examine only the databases affecting
the tablespace for objects instead of scanning all of them.
initdb forced
aggregates, conversions, functions, operators, operator classes,
schemas, types, and tablespaces. Fold the existing implementations
of alter domain owner and alter database owner in with these.

This eliminates the assumption that a serial column's sequence will
have the same name on reload that it was given in the original database.

creation of user-defined tablespaces with names starting with 'pg_', as
per suggestion of Chris K-L. Also install admin-guide tablespace
documentation from Gavin.
I kept the same abbreviated letter -D, in hopes of maintaining some
modicum of backwards compatibility (though it's doubtful whether anyone
is really using scripts that invoke createdb -D ...)
