Keep in mind then LIKE '%test_1' and LIKE 'test_1' are not equivalent, using the % as a prefix to the argument means that the scan only has to confirm that the value ends in 'test_1' where forgoing the % entirely means that you are essentially saying some_column='test_1'. -- View this message in context: http://postgresql.nabble.com/LIKE-pattern-tp5902225p5902701.html Sent from the PostgreSQL - performance mailing list archive at Nabble.com. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
