Greetings,
Immediately after an upgrade from 9.3.1 to 9.3.2, we have a client getting frequent (hourly) errors of the form:
/var/lib/postgresql/9.3/main/pg_log/postgresql-2013-12-12_211710.csv:2013-12-12 21:40:10.328

x86_64GNU/Linux.
Generally, there's no core file (which is currently enable), as the postmaster just normally exits the backend.
Diagnosis suggestions?
