Server 3.2.1 (10.9.5) – Postgres won't start

After upgrading from Server 3.1.2 (Mavericks 10.9.3) to Server 3.2.1 (Mavericks 10.9.5), I cannot start Postgres:

# serveradmin start postgres

postgres:error = "CANNOT_START_SERVICE_TIMEOUT_ERR"

Here is what I see in system.log:

Sep 18 18:36:20 server com.apple.serverd[78]: ERROR: SMJobSubmit: The operation couldn’t be completed. (kSMErrorDomainLaunchd error 9 - The job dictionary specifies that it is disabled.)

Sep 18 18:36:20 server serveradmin[2249]: servermgr_postgres: waiting for postgres to respond

Sep 18 18:36:24 server serveradmin[2249]: servermgr_postgres: Timed out trying to start postgres.

Sep 18 18:36:24 server serveradmin[2249]: posting dist not

Not sure what to do from here. Postgres was running fine under 10.9.3.
