Yes, because they are not really postmasters; they are child processes, which can be backends, the logger process, the background writer, etc. Try with this: ps u -C postmaster That should show more detail, and save you the "grep". Or try something like this: $ ps -w -C postmaster -o pid,ppid,args PID PPID COMMAND 15812 15808 /pgsql/install/00orig/bin/postmaster 15814 15812 postgres: writer process 15815 15812 postgres: stats collector process 15830 15812 postgres: alvherre alvherre [local] idle in transaction Here you can see that there is a postmaster with PID 15812, and several processes which are children of that one. -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support
