PostgreSQL 9.3 compatibility?

[kgeographer]

I've tried installing this extension into 9.3 and failed; unable to make without error and simply putting 9.1 library (.c, .so) in comparable 9.3 locations result in errors. Can I assume I'm doing something wrong, or is it not possible?

Separately, I know it's on Github, but do you have an interest to take this further with collaborators? Seems like a great starting point for the temporal datatype historians need -- plugging away at https://github.com/ComputingPlace/Topotime myself.
