Hi Dave, I use to shutdown the postgresql server by stopping the service, followed by that pgAgent server is automatically stopped.
However I am getting the following error message in service logger, while shutdown server. Postgresql Service error message The description for Event ID ( 0 ) in Source ( PostgreSQL ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: FATAL: terminating connection due to administrator command Pgadmin error message Failed to query jobs table! The PostgreSQL Scheduling Agent - pgAgent service terminated unexpectedly. It has done this 7 time(s). It looks like pgAgent is not properly shutdown as you said. Would you please help me how do I resolve this issue.

The only way I can see for that to happen is if the agent is killed whilst the job is being processed. That will cause the job's nextrun time to be reset during zombie clearance when the agent restarts. In the normal case, the job will be run as soon as the agent enters the main processing loop, where it will select all jobs with nextrun <= now() and process them immediately. -- Dave Page Blog: http://pgsnake.blogspot.com Twitter: @pgsnake EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgadmin-support mailing list (pgadmin-support@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgadmin-support
