The initial error message in this thread was not from me.

I am currently not in the office, but I will see if I can reproduce that tomorrow.

I have also contacted the SQL Workbench/J user who reported this to me last week
and asked him to describe his setup as well.

In his case, the error message was:

> FATAL: no pg_hba.conf entry for host "213.xxx.xx.xxx", user "foobar", database "postgres", SSL on

If I understood him correctly, he has no access to the server, so the only thing he did,
was to change the driver and he could connect again.
