Re: database lagging - Mailing list pgsql-admin
yes, I'm running replication database. Parameters below are on both master and slave's postgresql.conf
wal_level = replica
synchronous_commit = on
synchronous_standby_names ='*'
server storage is fine. Plenty of spaces on pg_wal (local), only 5% used from 80G. Look like only all write have problems and read is ok.

To call him a dog hardly seems to do him justice though in as much as he had four legs, a tail, and barked, I admit he was, to all outward appearances. But to those who knew him well, he was a perfect gentleman (Hermione Gingold)

I am doing CIS Benchmart on Postgreql 12. After alter parameters and when I tried to create a new role. It's lagging and didn't prompt out the result, until I hit the ctl C key. Even alter role.

I would only expect such a behaviour when there is Synchronous Replication enabled but the Standby is not reachable.
Check the parameters : synchronous_mode combined with synchronous_standby_names.
