This modification eleminates the case described below:
If PostgreSQL (probaly with Linux) was shut down wrong way (power off, any other damage, kill, etc... ) it left opened
thefile(socket) /tmp/.s.PGSQL.5432 . It is found by Postmaster's next start with message:
===
Starting postgresql service: FATAL: StreamServerPort: bind() failed: errno=98 Is another postmaster already
runningon that port? If not, remove socket node (/tmp/.s.PGSQL.<portnr>)and retry.
/usr/bin/postmaster: cannot create UNIX stream port
===
so, You are in situation that Linux was completely started, all services are running ok except the postgres - and if
Youmiss it, Your server can be running hours without poperly serving the database.
= = = = =
If You find it usefull, make following modification to the file:
/etc/rc.d/init.d/postgresql
on Your RedHat Linux (other Linux or Unix versions will probably need some changes in locations, filenames etc...)
Begin of the changed lines is marked # [B] added by daniel.peder@infoset.cz
End is marked # [E] added by daniel.peder@infoset.cz
other text stuff was left for Your better orientation where put the changes...
so here we are:
