GRRR! I wrote a quicky test program that bypasses the transaction processing
and just logs or skips the file. I can skip already-inserted files at
approximately 1,000 records per second, and insert new files into the
database at approximately 300 records per second.
It's obvious that I'm not having a PostgreSQL problem. I'm beginning to think
I have an interaction with a $^%@#$% piece of crap commercial device driver
installed on the system.
I thank you for your kind responses anyhow, even though it didn't turn out to
be a PostGreSQL problem.
