Well, I guess we disagree. But until we have a complete proposed
solution, we should leave environment variables on the table, since they
*do* allow some decoupling of logical and physical storage, and *do*
give the administrator some control over resources *that the admin would
not otherwise have*.

If a table name can have characters which are not legal for file names,
then how would you propose to support it? If we are doing a
restructuring of the storage scheme, this should be taken into account.

lockhart=# create table "one/two" (i int);
ERROR: cannot create one/two

Why not? It demonstrates an unfortunate linkage between file systems and
database resources.
