So far no luck reproducing any issue with this test case. I am running
two copies of import_loop.sh against the master, per your instructions,
and see occasional deadlock errors there as expected. No errors at all
on the standby though.

One question probably worth asking is what non-default GUC settings are
you using on the master and standby?

(BTW, for anyone else trying this: with multiple copies of
import_loop.sh you will get a lot of "duplicate key" failures with the
test as written. I had better luck after changing import.sh from
ts=$(perl -e 'print time')
to
ts=$$
ie use PID not timestamp as the pseudo-unique key. This could be made
more bulletproof yet, but it didn't seem worth more trouble.)
