I'm trying to start/stop the postgres database manager with a SysV init
script (RH4.2).
The script (following under - line numbers not included into original)
correctly starts postgres on runlevel 3 but it won't execute in order to
stop it on runlevel 0 and/or 6. The symlinks in /etc/rc.d/rc0.d and
/etc/rc.d/rc6.d are correct but it just won't execute.
If I replace the rc0.d/rc6.d symlinks with pre-existing ones (like gpm),
well, now the gpm-symlink-to-postgres.init stops the DB manager correctly.
This gives me the ideea that those symlinks should be 'registered' to some
file/service/daemon.
But I don't know where and/or how.
Any suggestions would be greatly appreciated.

PS: And by the way, given the line 42
su - ${PGACCOUNT} -c "(${POSTMASTER} ${PGOPTS} >& logger -p
${FACILITY}.notice) &" >& /dev/null&
how do I convert it from tcsh (which I know nothing about) to bash (which I
know very little about) ?
And even more
43 su - ${PGACCOUNT} -c "(${POSTMASTER} ${PGOPTS}) &" >&
/baza/postgres.session&
44 cat /baza/postgres.start > /baza/postgres.session
45 /sbin/clock -r >> /baza/postgres.session
works but if I change the order to 44,45,43 the lines 44 and 45 would
produce no output. Why ?
