Hi, After upgrade server to version 9.3.7 or 9.3.8 PostgreSQL doesn't start and complains like below: Jun 13 23:16:43 test postgres[1970]: [3-1] db=,user= FATAL: could not access status of transaction 1 Jun 13 23:16:43 test postgres[1970]: [3-2] db=,user= DETAIL: Could not open file "pg_multixact/offsets/0000": No such file or directory. Jun 13 23:16:43 test postgres[1966]: [2-1] db=,user= LOG: startup process (PID 1970) exited with exit code 1 I created this file: dd if=/dev/zero of=/var/lib/pgsql/data/pg_multixact/offsets/0000 bs=256K count=1 but... I do not know why it happened and whether this is the right solution? This cluster was upgraded via pg_upgrade from version 9.2 Best regards -- Andrzej Zawadzki -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
