Yes, it's called once with rank PROC_INIT, before forking
(so everything done here will be inherited by all the processes) and
another time with PROC_MAIN (here is the right place for forking other
processes that need tcp access).

DB connections should not be opened for PROC_INIT, PROC_MAIN or
Depending on what one wants to do with the DB connections, they might not
need to be opened also for PROC_RPC/PROC_FIFO/PROC_UNIXSOCK (but then no DB
access will be possible from the rpc/fifo interface) and maybe
PROC_TIMER (if you never use the DB connection from a timer).
