ipcclean(1) currently says:
| ipcclean cleans up shared memory and semaphore space from aborted backends
| by deleting all instances owned by user postgres. Only the DBA should
| execute this program as it can cause bizarre behavior (i.e., crashes) if
| run during multi-user execution. This program should be executed if
| messages such as semget: No space left on device are encountered when
| starting up the postmaster or the backend server.
AFAIR, with the 7.1 release the postmaster automatically recovers from
this situation. Can someone come up with a better description of what
ipcclean is useful for, if there still is such a thing?
