Log message:
    First phase of SCHEMA changes, concentrating on fixing the grammar and
    the parsetree representation.  As yet we don't *do* anything with schema
    names, just drop 'em on the floor; but you can enter schema-compatible
    command syntax, and there's even a primitive CREATE SCHEMA command.
    No doc updates yet, except to note that you can now extract a field
    from a function-returning-row's result with (foo(...)).fieldname.
