I'm going to modify initscripts and use a differente approach to probe
postmasters status, but I'm not sure if this is good:
ps ax | grep postmaster | grep /var/lib/pgsql2/data2
ps ax | grep postmaster | grep /var/lib/pgsql/data
What would you suggest?
pg_ctl -d /var/lib/pgsql2/data2 status
My experience is that you can not know if the database is running or has
died by only checking the status flag. But if you combines these two, by
checking the PID process ID from the pg_ctl command and then use 'ps
-ax' to see that this process is really alive, then you have a proof.
