Implement CREATE DATABASE/WITH LOCATION=.
Implement SET keyword = DEFAULT and SET TIME ZONE DEFAULT. Re-enable JOIN= option in CREATE OPERATOR statement (damaged for v6.2). Allow more SQL and/or Postgres reserved words as column identifiers or, if there are shift/reduce problems, at least as column labels.
