Do you mean LIKE in a query like this?
test=> EXPLAIN VERBOSE SELECT oid FROM pg_class WHERE relname LIKE 'pg_%'; QUERY PLAN
----------------------------------------------------------------------Seq Scan on pg_catalog.pg_class
(cost=0.00..12.80rows=230 width=4) Output: oid Filter: (pg_class.relname ~~ 'pg_%'::text)
(3 rows)
That would use textlike() in backend/utils/adt/like.c
