A very simple and incomplete example:
CREATE OR REPLACE FUNCTION new_table(int) returns bool AS
$$
BEGIN
IF $1 = 1 THEN
EXECUTE 'CREATE TABLE x()';
ELSIF $1 = 2 THEN
EXECUTE 'CREATE TABLE y()';
ELSE
EXECUTE 'CREATE TABLE z()';
END IF;
RETURN TRUE;
END;
$$
language plpgsql;
SELECT new_table(1);
Use EXECUTE and be sure you can't be the next victim of SQL injection.
If you need some userinput in the EXECUTE-statement, use
quote_literal() and/or quote_ident().
