Comment 13 for bug 1666566

src:postgresql-9.6 has transitioned, so now it's just removal of src:postgresql-9.5.

$ rmadison search -S postgresql-9.5 -s zesty | awk '{ print $1; }' | xargs -n1 reverse-depends | grep '^\*' | awk '{ print $2 }' | sort | uniq | xargs -n1 chdist bin2src zesty-proposed |sort | uniq

repmgr
$ rmadison search -S postgresql-9.5 -s zesty | awk '{ print $1; }' | xargs -n1 reverse-depends -b | grep '^\*' | awk '{ print $2 }' | sort | uniq | xargs -n1 chdist bin2src zesty-proposed |sort | uniq

barman recommends:

Recommends: openssh-server, openssh-client, postgresql-client | postgresql-client-9.6 | postgresql-client-9.5 | postgresql-client-9.4 | postgresql-client-9.3 | postgresql-client-9.2

So it is fine to leave as-is

repmgr (3.3.2):

Depends: postgresql-9.6-repmgr | postgresql-9.5-repmgr | postgresql-9.4-repmgr | postgresql-9.3-repmgr | postgresql-9.2-repmgr | postgresql-9.1-repmgr | postgresql-9.0-repmgr

but repmgr 3.1.5-1 is also in zesty. It shows up at
http://people.canonical.com/~ubuntu-archive/nbs.html and I think we need to manually delete the old binary package.
