Thread: pgsql: Update HINT for pre-existing shared memory block.

Update HINT for pre-existing shared memory block.

One should almost always terminate an old process, not use a manual
removal tool like ipcrm.  Removal of the ipcclean script eleven years
ago (39627b1ae680cba44f6e56ca5facec4fdbfe9495) and its non-replacement
corroborate that manual shm removal is now a niche goal.  Back-patch to
9.4 (all supported versions).
