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:
