Well, in such case it means that the best possible option is to name every
postgresql package including it's version number (postgresql-server73,
postgresql-server74, postgresql-server80 -- this won't be a big problem if
the base metapackage will have enough configureable options) and to make it
install every single file in a separate directory hierarchy
(${PREFIX}/pgsql72, ${PREFIX}/pgsql73). Data directory could be located
inside that hierarchy. Such action would also need to test every
postgresql-lib or postgresql-client dependent package.

Anyway, I feel this could do some more harm. Anyone would like to comment?
