Thread: pgsql: Handle EACCES errors from kevent() better.
Handle EACCES errors from kevent() better. While registering for postmaster exit events, we have to handle a couple of edge cases where the postmaster is already gone. Commit 815c2f09 missed one: EACCES must surely imply that PostmasterPid no longer belongs to our postmaster process (or alternatively an unexpected permissions model has been imposed on us). Like ESRCH, this should be treated as a WL_POSTMASTER_DEATH event, rather than being raised with ereport(). No known problems reported in the wild. Per code review from Tom Lane. Back-patch to 13.
