Service upgrade: apigee-postgresql Stopping apigee-postgresql: apigee-service: apigee-postgresql: OK pg_ctl: PID file "/opt/apigee/data/apigee-postgresql/pgdata/postmaster.pid" does not exist Is server running? Error: update.sh: /opt/apigee/apigee-service/bin/apigee-service exited with unexpected status 1
Is this happening when you start the update? Or after you've finished it?
The error is basically saying that the server seems to be running but there is no pid file.
