Comment 2 for bug 290648

Spoke to upstream about this package, along with the discussion in the debian bug he adds,

"The benefit of allowing people who use ruby-postgres directly (as opposed to a wrapper layer like Ruby/DBI or Rails/Active Record) to postpone the migration is not worth the costs: supporting an obsolete package with dead upstream, extra load on package archive and mirrors infrastructure, user confusion due to having two almost but not exactly similar libraries performing the same job."

I agree, I don't believe that adding an ubuntu package for the obsolete library or forking the libpgsql-ruby package in ubuntu is worth the effort.
