This is a problem with the newer versions as well. Maybe even worse,
as we had to do some contortions when the PQprepare 7.4/8.0 mess
appeared. However, we can definitely speed up that part of the code.
I'll see about doing this soon.

I still maintain the original test is brain-dead, however. :) It was
testing for "insert speed" by basically doing this:

for (1..1000) {       $dbh->do("INSERT INTO testtable(a,b) VALUES (1,2)");
}

It's as if the people who wrote it *cough*mysql*cough* never heard
of prepare/execute and did not read the DBI docs.

It's very similar to the script on this page:
