Sounds like a very nice improvement.  It would also benefit those of us,
who want to run different PostgreSQL versions in parallel.  I say go for

Just one question: in case of new major release, what would happen to
SlackBuild for the old one?  Would it be removed from SBo?  PostgreSQL
community maintains 4 to 5 versions at the same time, but I guess this
would be too much for a single SBo maintainer.  Not that I need this
(I'm already grateful for the current PostgreSQL SlackBuild), just
something to think about.
