Postgrest Not Recognizing New Columns Or Functions Bd75f5

If PostgREST is returning errors by not recognizing new database columns, tables, views or functions, and logging errors similar to:

24/Dec/2025:18:16:33 -0500: Failed listening for database notifications on the "pgrst" channel. ERROR:  could not access status of transaction 12037872 DETAIL:  Could not open file "pg_xact/000B": No such file or directory.

Then this indicates that there's a stale PostgREST schema cache.

Why this happens

This can occur when an underlying Postgres notification queue issue prevents PostgREST from receiving cache reload signals after schema changes.

How to fix this

Execute the following SQL command via the SQL Editor or a direct client:

select pg_notification_queue_usage();

This command directly refreshes the Postgres notification queue, prompting PostgREST to update its schema cache with the latest database schema. This process is non-disruptive and does not require a database instance or PostgREST service restart.
