I see in the source code that there are "init scripts" for Oracle and
PostgreSQL as well...  This may bode either well or ill...

The "ill" part is that when you build to be "totally generic," then
you have to eschew any features that aren't available everywhere,
which, in this case, tends to rule out relational integrity (e.g. -
foreign keys) or having constraint validation.

I did notice the "sin" of tables with scores of columns.  The
alternative, alas, is usually the EAV sin, which I think I'd *less*
rather see...
