I am trying to run a query which was working a few weeks ago, and it utilizes the <<-> operator but I am getting an error: operator does not exist text <<-> text.
If I try instead the function word_similarity() I get a similar (no pun intended) error: function word_similarity(text, text) does not exist.
If I try to install the pg_trgm extension with `CREATE EXTENSION pg_trgm;` I get an error: extension "pg_trgm" already exists.
Running PostgreSQL 10.1, compiled by Visual C++ build 1800, 64-bit
Any ideas? Thanks,
