Drop the final dependency on the Postgres test_parser extension. We also have to remove references to test_parser in the migration where it was first defined, otherwise replaying all migrations from the beginning will fail. Replaying all migrations from the beginning normally isn't done except in testing. After this, it should be possible to use a vanilla install of Postgres with Danbooru. It's still recommended to use Danbooru's Docker image for Postgres (https://ghcr.io/danbooru/postgres), as other Postgres extensions may be necessary in the future.
