Resources that use the AshPostgres data layer use a Repo to access the database.

This repo is a slightly modified version of an Ecto.Repo.

You can use Ecto.Repo's init/2 to configure your repo like normal, but instead of returning {:ok, config}, use super(config) to pass the configuration to the AshPostgres.Repo implementation.

Currently the only additional configuration supported is installed_extensions, and the only extension that ash_postgres reacts to is "pg_trgm". If this extension is installed, then the AshPostgres.Predicates.Trigram custom predicate will be available.

def installed_extensions() do
  ["pg_trgm"]
end
