Re: psql: Fix CREATE SCHEMA scanning of nested routine bodies

Pushed with some mostly-cosmetic changes.  Notably, I renamed the
existing "identifiers" field to help distinguish it from the new one.

I didn't use your test cases because it seemed unduly expensive to do
it that way.  We can perfectly well exercise this as part of plain-SQL
regression testing, so I just added a booby-trap case in
create_schema.sql.  Without this fix, psql marches on and tries to run
the various \d commands after the CREATE SCHEMA before it's sent the
CREATE SCHEMA command.  So even though no error is reported, the
output is quite different.
