We currently use partitioning by date and id, with 1/4 a year of dates and
approximately 10 IDs (and slowly increasing).  Each partition runs from
around 1 million to 20 million rows.

Whether it's recommended or not, I don't know.  But for us, the partitioning
works exactly as advertised.  As with anything new, I'd take the time to
setup a simple test to see if it works for you, too.

In particular, be sure to check the documentation on caveats.  You'll find
these a little stricter than partitioning issues in Oracle or SQL Server.

HTH,
Paul
