Interesting. I wouldn't have though that expanding the heap was such a slow operation.

I wrote this test so I could compare JDBC and psql side by side. My real application uses
a cursor and the memory doesn't get so big.

That's what I used to do, but it makes the code cleaner to use getFetchSize(). Seems to
work all the time for me.
