I checked for performance impact compared to master with pgbench -S,
and didn't see any problem. I thought more about how to write a
decent race-free test but struggled with the lack of a good way to
control multiple connections from TAP tests and gave up for now. I
previously tried to write something to help with that, but abandoned
it because it was terrible[1]. It seems a bit strange to me that psql
has to be involved at all, and we don't have a simple way to connect
one or more sockets and speak the protocol from perl.
Pushed! Thanks to all who contributed.
