CREATE tab completion

Hi hackers,

I noticed that there are some tab completions missing for the following 
commands:
-CREATE CONVERSION : missing FOR, TO, FROM
-CREATE DOMAIN : missing after AS
-CREATE LANGUAGE : missing after HANDLER
-CREATE SCHEMA : missing AUTHORIZATION, IF NOT EXISTS
-CREATE SEQUENCE : missing AS
-CREATE TRANSFORM : missing after FOR

I made a patch for this, so please have a look.

Best wishes,
