-- This script disables use of the new LIKE-related selectivity estimation
-- functions, which are a little too new to be enabled by default in 7.0.
-- You can enable them again by running enablelike.sql.

-- Use of the functions will be disabled only in those databases you
-- run this script in.  If you run it in template1,
-- all subsequently-created databases will not use the functions.

-- Be sure to run the script as the Postgres superuser!
