I'm not sure what you mean about auto-detecting the version -- I assume
we would auto-detect the version by calling pg_config from the
configured path and parsing the binary, which is what Mark's patch is
supposed to do already. So I don't see what the distinction between
those two things is.
In order to avoid having an ever-growing plethora of 100-byte .pm files,
we can put the version-specific classes in the same PostgresNode.pm
file, at the bottom, "class PostgresNode96; use parent PostgresNode10;"
followed by the routines that are overridden for each version.

Let's give it a try ...
