I can reproduce the bug by installing wheezy, starting postgres and upgrading libc6(2.13 to 2.19). After that peer authentication does not longer work.
logfile says: "local user with ID 110 does not exist" It looks like getpwuid() is broken after the libc6 upgrade. In postgresql/src/backend/libpq/auth.c:1793 the function getpwuid(uid) returns NULL and triggers the error message. A really simple solution should be to add the following line to "eglibc/debian/libc.postinst:102". check="$check postgresql-8.4 postgresql-9.1 postgresql-9.2 postgresql-9.3" This leads to a restart of postgres after an libc6 upgrade and fixes the problem. It should not be necessary for smaller changes and bug fixes. So it would be ok to trigger a restart only by performing major upgrades. Should restarting postgres be the default after any libc6 upgrade or is there a better way?
