advice for user column named cmin

I'm trying to use a closed source program with PostgreSQL over ODBC

The problem is that it tries to make a table which has a column called
'cmin' which of course not allowes.

Are there any plans of either

1) (optionally) renaming such sytem columns in the ODBC layer

2) renaming system colums to start with pg_ (pg_oid, pg_cmin, pg_*)

3) moving them to another namespace, accessible like a schema

so

select oid from mytable;

would become

select system.oid from mytable;

I quess that SQL is not as flexible as XML in putting anything in its
own namespace ;(
