You realize that's from 2007?

There wasn't any checkpointer back in 2007. These days the filter step
of my script looks like

grep -v -e 'grep postgres:' -e 'postgres: stats' -e 'postgres: writer' -e 'p
ostgres: wal writer' -e 'postgres: checkpointer' -e 'postgres: archiver' -e 'pos
tgres: logger' -e 'postgres: autovacuum' | \

In any case you could (and should) have just done "attach 13379" to get
control of the process you wanted. The "ps | grep" dance is just an
aid, not something that is guaranteed to work every time.
