CockroachDB Gin String Indexes

[FxEasy]

CockroachDb allows for gin indexes on string types using the gin_trgm_ops function which comes with it.

In the provided github link we check if the value is a certain type to allow the GIN operator.

There should either be extra handling for psql and cockroachdb to support this gin_trgm_ops function on top of the Gin index to allow for string types to be indexed properly using a Gin Trigram; or a workaround to not error when it's used in the schema itself.
