It seems that after latest 2.0.45 upgrade this plugin started showing
values without any manual changes.

I see "1" Active connection, and ~25 "Waiting for lock", while
postgres_connections_db plugins shows ~25 for that DB, so maybe that's OK.

"Waiting for lock" is strange naming though, I would expect it more like
"Idle" or "Idle in transaction", as I would imagine waiting for lock a
contention event, and I doubt it's the case, but I am not PostgreSQL expert

It would be nice to have some sort of integration tests for these kind of
plugins to test correctness.
