Thanks Bruce

I tried to do that and it worked just fine the first time, and after that I
wrote "ipcs" to get a statistical if it really was cleaned or not, but I
got this ->

Message Queues:
T ID KEY MODE OWNER GROUP

Shared Memory:
T ID KEY MODE OWNER GROUP
m 1376259 0 --rwa------ postgres postgres
m 131076 0 --rw------- postgres user
m 786437 0 --rw------- postgres postgres

Semaphores:
T ID KEY MODE OWNER GROUP

Now I tried to use "ipcclean" once again, and I am always getting these
errors ->

ipcrm: shmid(1376259): : Invalid argument
ipcrm: shmid(131076): : Invalid argument
ipcrm: shmid(786437): : Invalid argument

I have no idea why, except maybe this could be something that is left over
since old and now the system doesn't know how to remove this Postgres stuff.

If anyone have any clue about what I can do, please let me know, I would
appreciate it a lot.
