Hi!
Got it. Just thought it would be easier not to have to deal with cross OS issues.Here is one example: https://www.pgpool.net/docs/latest/en/html/example-watchdog.html
Hopefully Windows Hyper-V virtual network adapter will not check windows 20 connection limit. In this case using Debian+Hyper-V+ binary replication allows to connect more than 20 users and may be best solution.
Both have 64-bit OS. Will binary replication work in this case.Andrus.
