Not sure this is a bug, but I'm seeing the following message: pg_ctl: another postmaster may be running; trying to start postmaster anyway FATAL: pre-existing shared memory block (key 9812001, ID 655374) is still in use HINT: If you're sure there are no old server processes still running, remove the shared memory block with the command "ipcclean", "ipcrm", or just delete the file "postmaster.pid". pg_ctl: could not start postmaster Examine the log output. pg_ctl: neither postmaster nor postgres running
However, ipcs shows there is no shared memory block in use: $ ipcs ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x00000000 327682 root 644 151552 4 dest 0x00000000 360453 root 644 122880 4 dest 0x00000000 393222 root 644 790528 4 dest 0x00000000 720910 ed 666 42900 1 dest ------ Semaphore Arrays -------- key semid owner perms nsems ------ Message Queues -------- key msqid owner perms used-bytes messages ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
