pgsql: Add some knowledge about prefix matches to tsmatchsel(). - Mailing list pgsql-committers

Log Message:
-----------
Add some knowledge about prefix matches to tsmatchsel().  It's not terribly
bright, but it beats assuming that a prefix match behaves identically to an
exact match, which is what the code was doing before :-(.  Noted while
experimenting with Artur Dobrowski's example.
