Considering that the system catalogs alone occupy about 5MB per
database, that would require an impressive amount of storage...
In practice I think users would be complaining about our choice
to instantiate the catalogs per-database a lot sooner than they'd
hit the subdirectory-count limit.
BTW, there is another avenue that the OP could look into if he
really wants this many databases on a UFS filesystem: split them up
into multiple tablespaces.
