Or can use the latest, which appears to be 9.5 on 16.04? For binary streaming replication, the major version has to match. But you aren't constrained to using the major version that ships with Ubuntu: you could also use the community packages from here: https://wiki.postgresql.org/wiki/Apt The packages work the same way and as far as I know the same people are involved in maintaining them. BTW The latest 9.1.x is actually 9.1.21, and that major version reaches EOL pretty soon: http://www.postgresql.org/support/versioning/ -- Thomas Munro http://www.enterprisedb.com -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
