Bucardo shows wrong postgres version

Question

I'm installing Bucardo to replicate my Postgres server (10.1) on openSUSE Leap 42.3, and I have successfully complied the executable of Bucardo. When I tried bucardo install and modified the parameter as:

host:<none>
port:5432
user:aSuperUser
database:bucardo
piddir:/tmp/bucardo (already created)

Bucardo says: Postgres version is 4.8. Bucardo requires 8.1 or higher. How could this happen? I installed postgres 10, not 4.8. I also verified the version by select version(); and, there is only one postgres installation on my machine.

It seems to be fixed in master. There is a thread in the bucardo-general mailing list, that explains that you can make by yourself a couple of changes in the bucardo script or apply the diff:

The bucardo script is in /usr/local/bin/bucardo and does not have write permissions so you must change it.
