My little enumkit tool allows you to create enumerations today very

trick still works. The downside is that each enumeration type requires a
tiny bit of compilation.

A simpler way to do this might be to only cache the list per query
context. In your IO functions, you could whack a pointer to your cache
onto fcinfo-flinfo-fn_extra, and the same flinfo gets passed in for
e.g. all output function calls for that column for that query, IIRC.
This was what I had
As far as memory management goes, do I just use hash_create() and assign
that pointer to fn_extra and at the end of the query it will be freed?
Or will it not be freed until this end of the transaction? I'm really
having trouble understanding the memory management issues with Postgres.

Look at the dynahash code. I just used it for the first time in a plperl
patch, and it's reasonably
