Yeah, it's tough to do that in a few of those such as validator
functions, and I don't think we'd want to do that.  However there are
some cases where we can easily add the parsestate as an argument -- for
example CreatePublication can get it in ProcessUtilitySlow and pass it
down to parse_publication_options; likewise for ExecuteDoStmt.  I didn't
check other places.
