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