If the user does not have the necessary privileges to create the table you might want to use SECURITY DEFINER.

Some if not exists context would help. –Kev Jan 12 '09 at 14:05 Hey, check my code :-) it only create the table if it does not already exists –Michael Buen Jan 12 '09 at 15:17 add a comment| 10 Answers 10 active oldest votes up vote 55 down vote I'm not sure when it was added, but for the sake of completeness I'd like to point out that in version 9.1 (maybe before) IF NOT EXISTS can be used. IF NOT EXISTS will only create the table if it doesn't exist already. Example: CREATE TABLE IF NOT EXISTS users.vip ( id integer ) This will create a table named vip in the schema users if the table doesn't exist.

Description The PostgreSQL CREATE TABLE statement allows you to create and define a table. Syntax In its simplest form, the syntax for the CREATE TABLE statement in PostgreSQL is: CREATE TABLE table_name ( column1 datatype [ NULL | NOT NULL ], column2 datatype [ NULL | NOT NULL ], ... ); However, the full syntax for the PostgreSQL CREATE TABLE statement is: CREATE [ [ GLOBAL TEMPORARY | GLOBAL TEMP | LOCAL TEMPORARY | LOCAL TEMP | UNLOGGED ] TABLE [IF NOT EXISTS] table_name ( column1 datatype [ COLLATE collation ] [ CONSTRAINT constraint_name ] { NULL | NOT NULL | CHECK ( expression ) [ NO INHERIT ] | DEFAULT default_value | UNIQUE index_parameters | PRIMARY KEY index_parameters | REFERENCES ref_table [ ( ref_column ) ] [ MATCH FULL | MATCH PARTIAL | MATCH SIMPLE ] [ ON DELETE action ] [ ON UPDATE action ] } [ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ], column2 datatype [ COLLATE collation ] [ CONSTRAINT constraint_name ] { NULL | NOT NULL | CHECK ( expression ) [ NO INHERIT ] | DEFAULT default_value | UNIQUE index_parameters | PRIMARY KEY index_parameters | REFERENCES ref_table [ ( ref_column ) ] [ MATCH FULL | MATCH PARTIAL
