[Pkg-postgresql-public] Bug#641278: Still present in 9.1.4-2

E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
Setting up postgresql-client-9.1 (9.1.4-2) ...
update-alternatives: error: alternative pg_basebackup.1.gz can't be slave of psql.1.gz: it is a slave of postmaster.1.gz

dpkg: dependency problems prevent configuration of postgresql-contrib-9.1:

Errors were encountered while processing:
 postgresql-client-9.1
 postgresql-9.1
 postgresql-contrib-9.1

This is caused by having the 9.2 betas on the machine as well.  I thought
the idea was that it was possible to have both?
