Re: pgAgent for multiple databases in same instance

So my experience isn't with pgagent directly, because I have been using my
re-written version of it for ~5 years (but at least at one point I had a
pretty darn good understanding from doing that rewrite)...please take this
with a grain of salt if I am incorrect on anything.

So the agent is only able to connect to a single "db" at a time, so you are
correct you'd need to run multiple agents (connected to the different db's)
to have things work as you intended.

What is the reason for creating the pgagent extensions in multiple
databases? The extension itself is the storage / logs / job definition, so
each extra one is totally detached from the rest. You can still use a
single pgagent install to connect to many databases to do work, so I am
just not sure why you'd need multiple.
