Right.

Does any other 3rd party tooling for Postgres do that? I assume the
client will get the connection failure and, upon reconnection, will get
a good new connection, essentially failing over to the next host. Oracle
has "Transparent Application Failover", but that's a pretty high bar I
am not sure anybody is expecting us to jump over just now.

I phrased it "connection-based client-side failover" in another mail,
would emphasizing that it is at connection granularity be enough to
address your concerns? The pgJDBC called the (AFAICT) identical feature
"connection failover" in their changelogs for 9.3-1100 and 9.4-1200:
