Hi

in verbose logs I found messages that the pgsql resource agent on running
master is notified with pre/post stop operation when second node connects
and the monitoring operation on master is cancelled.

in my log "ifds1" is master and "ifds2" slave (or slave candidate)

but why is the pgsql RA on master monitoring cancelled?
