It is possible that due some weird stuff the port is not made free...
check with
$ netstat --all --numeric-ports -p | grep 5432
this -for example- is my output:
tcp 0 0 0.0.0.0:5432 0.0.0.0:*
LISTEN 12775/postmaster
unix 2 [ ACC ] STREAM LISTENING 24015
12775/postmaster /tmp/.s.PGSQL.5432
If there is output, then check the PID which is just before the slash,
in this case 12775
$ ps 12775
output:
PID TTY STAT TIME COMMAND
12775 ? S 0:00 /usr/local/pgsql/bin/postmaster -i
As you can see: there is a postmaster running
You might want to try to kill -TERM the process... don't use kill -KILL
(or kill -9) on a running database, as you may very well very much
damage your database...
Don't use kill -SEGV either! It's even more devastating...
kill -TERM is a request to shutdown as soon as possible. The process is
allowed to shut down nicely and neatly.
kill -KILL is an order to stop immediately. There's no buffer flushing,
finishing writes etc etc
kill -SEGV tells the program it made a segmentation fault and it crashed
(core dump situation)
hope this information helps...
