If that also implies a large number of tables, you might start to run
into filesystem-level bottlenecks due to having a large number of files
in the same directory. If you aren't using a filesystem that copes
gracefully with huge directories, you probably want to avoid having more
than a few thousand files per directory. (As of PG 8.0 you can work
around this to some extent by segregating tables into different
tablespaces.)
