Your request is essentially to wrap the GMP library into native types in Postgres. This can be done as custom types and adding postgres extensions as you suggested originally. The work to be done is straightforward, but there is a lot of work so it would take a awhile to implement. The big integer part is rather simple, while there is some work to be done there the fractional part will take significantly longer because reasons ( think testing edge cases), but it is doable if there is interest in implementing this.

Dear PostgreSQL Hackers,
I have been trying to get a reply or interest in either updating
PostgreSQL to support High Precision mathematical types,
with arithmetic and elementary functions support, or release
of an Extension which has accomplished the same thing.
Is there someone on this email list which could please have a look
at the specifications that I have posted, and reply and get back to
me? I would be more than thrilled if something could be done
to improve PostgreSQL in this area.
Yours Sincerely,
Z.M.
