Renewing LISTEN command in Postgres Adapter

[miriam-kismet]

I'm using the Postgres adapter to maintain consistency across multiple instances of a Google Cloud Run service. For some reason, it seems like the LISTEN/NOTIFY functionality occasionally just stops working, and when we scale to multiple instances, events just get lost.

One recommendation I was given when I asked about this in the gcloud forum was to periodically renew the LISTEN query. Is that possible from within the adapter? I don't see a good way to do it.
