Fastest method to insert data.

What would be the fastest way to insert a bunch of data (in 7.1)?
Currently, a bunch of addBatch()es followed by executeBatch() is pretty
fast, but not as fast as COPY TABLE via psql.  I suppose I can use a single
executeBatch() to insert the entire table, but AFAIK addBatch() just buffers
the SQL in memory, and I prefer to have some kind of an upper limit on my
memory footprint.
