pgsql: Fix grammar for IN/OUT/INOUT parameters. - Mailing list pgsql-committers

Log Message:
-----------
Fix grammar for IN/OUT/INOUT parameters.  This commit doesn't actually
implement any new feature, it just pushes the 'not implemented' error
message deeper into the backend.  I also tweaked the grammar to accept
Oracle-ish parameter syntax (parameter name first), as well as the
SQL99 standard syntax (parameter mode first), since it was easy and
people will doubtless try to use both anyway.
