Sorry to have left this hanging so long, but I was off sick all last week.

We started with the loglevel=3D2 option in the driver. We ran for a few se=
conds and got about 620KB of output, including 15 of these. I'm starting t=
o pore over them, but I'm not sure what I'm loooking for. I've never read =
one of these puppies before. Any documentation out there to help? Any tip=
s? I assume you don't want a 620KB attachment to an email to this list.

Thanks,

tcpdump will do the trick (something like 'tcpdump -n -w
some.output.file -s 1514 -i any tcp port 5432')
Or you can pass '&loglevel=3D2' as part of the JDBC connection URL to have
the JDBC driver generate a log of all the messages it sends/receives (in
less detail than a full network-level capture would give you, though)

No, the JDBC driver waits for ReadyForQuery from the backend before
returning.
