In order to satisfy my own curiosity I decided to take a stab at this which
turned into the attached. I wasn’t able to reliably know that the pg_sleep
query had started except letting the timer expire, but that may very well be
the rust on my Perl skills showing.
Not sure if this moves the needle on this in either direction, but I figured I
should report back progress either way.
