How about origin/subscriber? More descriptive than primary/secondary,
and less tied to a particular model of interaction.

Cheers,
David.

Primary/secondary seem like a poor choice because they're such generic
terms. Master/slave is the common terminology for this, I think,
though some might object on grounds of political incorrectness.
If so, master/standby would probably work.

Yes but completely out of scope within the market. Master/Slave or
Master/Standby is probably where it needs to be.

+1 for master/standby.

It's worth remembering that a "standby server" might not be actively
connected to a master server. A server that's reading WAL from an
archive backup, for example, can be put to standby mode. "Standby"
covers that case too, better than "slave".

So does this mean we should rename primary_conninfo?
