[Pljava-dev] uuid datatypes and prepared statements

[Lucas Madar]

I found a workaround, but I'm not sure if there are any bad side effects 
to doing it this way: (other than it being ugly)

Before I do any queries with Java UUIDs, I do:
         Oid.registerType(UUID.class, new Oid(2950));
(2950 is the 'magic number' OID from postgresql's types.h)

This seems to have the effect of letting JDBC map Java native UUIDs to 
Postgresql UUIDs.
