34 longDescription = ''
35 pg_similarity is an extension to support similarity queries on PostgreSQL. The implementation
36 is tightly integrated in the RDBMS in the sense that it defines operators so instead of the traditional
37 operators (= and <>) you can use ~~~ and ~!~ (any of these operators represents a similarity function).
