were those postgres servers installed via yum?

if so, then simply doing...

     yum update postgresql91

followed by....

     service postgresql-9.1 restart

on each machine should suffice.   I believe the recommended order is to
upgrade the streaming slave first, then the master.  I don't know if
Slony matters either way (I've never used it)

when doing minor upgrades, you should always read ALL the release notes
for the versions greater than your existing and up to the new one you'll
be installing.   Looking at
http://www.postgresql.org/docs/9.1/static/release.html I see a couple of
the updates require reindexing, also some modifications to citext stuff
if you're using that.
