17 * This SQL statement installs an always-secure search path, so malicious
18 * users can't take control. CREATE of an unqualified name will fail, because
19 * this selects no creation schema. This does not demote pg_temp, so it is
20 * suitable where we control the entire FE/BE connection but not suitable in
21 * SECURITY DEFINER functions. This is portable to PostgreSQL 7.3, which
22 * introduced schemas. When connected to an older version from code that
23 * might work with the old server, skip this.
