citext contrib module (building indexes) - Mailing list pgsql-general

I've got several columns in my database that need to have case insensitive searches done so I've loaded the citext control module and have changed the data types to citext.  When I create a index on a column that is defined as a citext, how is that going to be treated.  Will Postgres use the index to search or will it always do a table scan?

Best Regards
