-DROP FUNCTION IF EXISTS to_tsvector(IN document weighted_text);

+-- There is no need to drop to_tsvector() explicitly, as we can rely on "DROP
+-- TYPE IF EXISTS weighted_text CASCADE" statement below, which will drop all
+-- objects that depend on this type. Moreover this DROP FUNCTION statement will
+-- fail for old versions of PostgreSQL (experienced for 9.2.14) with error:
+-- type "weighted_text" does not exist.
