As Fred mentions later in the thread your issue here is twofold. One
is that Rails isn't correctly understanding 'infinity', that's
obviously postgresql specific and has no parallel in ruby itself (as
you said). That'll never be fixed.
Actually, it turn out that 'infinity' is supported in Ruby.
Apparently infinity can be represented by assigning the value obtained
by dividing a float by zero.
$ irb
ruby-1.8.7-p334 :001> infinity = 1.0/0
=> Infinity
ruby-1.8.7-p334 :002> ninfinity = -1.0/0
=> -Infinity
ruby-1.8.7-p334 :003>
So, I guess this now qualifies as a bug in the Ruby pg adapter gem.
FWIW - you don't have to divide by zero to get infinity. You can use
Float::INFINITY.

=> true
