This new version of the patch adds support for
During FOSDEM, I discussed with Heikki about some interesting (at least
for us) informations: mainly knowing who the master is and knowing who
the slaves are.
He confirmed me there is actually no way to get that information.
There's also no way to have the contents of recovery.conf available as
all other GUCs. We found that we could at least read the recovery.conf
file in the master with pg_file_read, which will give us the master host
(via the primary_conninfo parameter) for people using the adminpack
module contrib. Is it something interesting enough that I put some time
to code this? or do we stop here, commit what I already have and see
later what's coming next? (the "what's coming next" could be something I
would code for next release)
