You can think of "md5" inside pg_hba.conf as "md5 or better" As a result, some users are able to connect, while others cannot. Can you expand on this? Nothing you have done should be preventing logins, as far as I can tell. Best solution: Upgrade everyone to scram, then change md5 to scram in pg_hba.conf and never look back. -- Cheers, Greg -- Crunchy Data - https://www.crunchydata.com Enterprise Postgres Software Products & Tech Support
