Compile with LANG support and set the LANG environment variable for the
postmaster. Restart the postmaster.

Then you get your own currency symbol:

junk=> select * from moneybag;
who|amount
---+-------
A |£250.00
(1 row)

But I don't like the fact that this has to be done in the backend. It
means that the currency of money is tied to the LANG environment of the
postmaster, rather than to the data itself. One of the characteristics of
money is the currency in which it is denominated; this ought to be part
of the datatype. It would then be invalid to perform arithmetical
operations between different currencies, which would correctly reflect
the real world.

Therefore, I propose that the money type be extended to include a
currency definition, the default being that of the backend environment.
