Troubleshooting "permission denied for database postgres"

[kjcsb1]

PostgREST 12.2

I'm connecting PostgREST to a restored database from a dump created using pgdumpall. The source database has a PostgREST instance successfully connected. However PostgREST returns a permission denied for database postgres message. I feel like I'm missing something obvious. Any suggestions appreciated.

permission denied for database postgres

It looks to me that the user does not have connection permissions to the database. Perhaps it has to do with a pg_dumpall option (e.g. the -x option does not migrate privileges). Check if you you can connect to the database with psql and your "authenticator" user.

If not, try granting connection privileges and such:

GRANT CONNECT ON DATABASE postgres TO your-authenticator;

If that's so, check if your pg_dumpall is migrating the permissions correctly.
