On May 22, 2015, the PostgreSQL Global Development Group released an update to all supported versions of PostgreSQL, including versions 9.4.2, 9.3.7, 9.2.11, 9.1.16, and 9.0.20. This update has a bug in fsync logic which will cause some users' PostgreSQL servers to refuse to restart after a crash, or after a restore from binary backup. Please read our FAQ on this issue (https://wiki.postgresql.org/wiki/May_2015_Fsync_Permissions_Bug) before applying the update to your systems.
The PostgreSQL Project regrets the error. Another PostgreSQL update, with this issue corrected, will be released soon. -- Sent via pgsql-announce mailing list (pgsql-announce@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-announce
