Re: repmgr 3.x releases in Postgres PPA for Ubuntu Trusty

Hi Marco,

   We've taken the decision to upgrade to repmgr 4.x because sticking
with the old version is complex and leaves us 'frozen in time' without
any updates etc..

Unfortunately, I've hit a show-stopped bug in version 4 :-(   The repo
gives us 4.0.0-2.pgdg14.04+2 but the SQL query for 'repmgr cluster show'
is broken. We don't use the 'repmgr' user and have fallen foul of the
oversight which is fixed the following commit:

| * commit 3e4a5e6ff5f386391c06aa639fbd8ff6299e1db6
| | Author: Martín Marqués <martin(dot)marques(at)2ndquadrant(dot)com>
| | Date:   Wed Nov 22 17:13:58 2017 -0300
| |
| |     Fix missing FQN for the nodes table.
| |
| |     This bug was not detected before because most users work with
the repmgr
| |     user. For that reason, the repmgr schema is already in the
search_path
| |     by default.
| |
| |     Add the repmgr schema to the nodes table in the LEFT JOIN used for
| |     cluster show (and in other places)

The above commit is is rolled up into v4.0.1 so do you know when this
will be released to the PPA please?

Thanks
Jonathan
