Thread: BUG #12819: CREATE TYPE fails within CREATE SCHEMA
The following bug has been logged on the website: Bug reference: 12819 Logged by: Chris Craig Email address: postgresql.org@ciotog.net PostgreSQL version: 9.3.5 Operating system: Ubuntu 14.04.1 LTS Description: When creating objects within a CREATE SCHEMA definition, "CREATE TYPE" fails with 'ERROR: syntax error at or near "TYPE"'. Eg: postgres=# CREATE SCHEMA foo postgres-# CREATE TYPE foo.bar AS ENUM('ONE','TWO','THREE'); ERROR: syntax error at or near "TYPE" LINE 2: CREATE TYPE foo.bar AS ENUM('ONE','TWO','THREE'); ^

That's not supported; per the manual, we only allow these things within a run-on CREATE SCHEMA: Currently, only CREATE TABLE, CREATE VIEW, CREATE INDEX, CREATE SEQUENCE, CREATE TRIGGER and GRANT are accepted as clauses within CREATE SCHEMA. That's basically driven by what was required in SQL92. It's unlikely that we're going to worry about extending that set much, because the lack of separating semicolons means that we risk syntax ambiguities anytime we add more options. We could only resolve such problems by making more keywords fully reserved, which is a disadvantage that greatly outweighs any value anyone might see in this syntax for CREATE SCHEMA. My advice: use a simple CREATE SCHEMA and separate commands for the contained objects. You can wrap the whole thing in a transaction if you're concerned about making it atomic. regards, tom lane

CREATE and GRANT are both fully reserved already; what potential ambiguities are introduced by adding more CREATE statement variants to that list? (all the spec's clauses for the body of CREATE SCHEMA begin with either CREATE or GRANT) -- Andrew (irc:RhodiumToad)
