Sooo. This time, I wasn't able to find freeze for 1s. But I found
a cluster with ~ 600ms freezes.

Ran tight-ish loop of pg_sleep(0.05):

| #!/usr/bin/env bash
| (
| echo '\timing'
| while true
| do
| echo "SELECT now(), pg_backend_pid(), pg_sleep(.05);"
| done
| ) |
| psql -qAtXF, |
| perl -ne '
| if (/^(.*),(.*),\s*\z/) {
| printf("%-30s :: %6s :: ", $1, $2);
| } elsif (/^Time: (\d\d+)\.(\d+) ms\s/) {
| printf "%s.%s ms :: %s\n", $1, $2, "#"x$1
| }
| '

and it logged:

This time, on this cluster, the problems seemes to happen ~ 10 minutes apart.

Got strace of startup, and of pg backend that did it.

First, the backend processing pg_sleep:
