I tried that. Whether I issue the VACUUM VERBOSE call through JDBC
or psql, I don't see anything in the postgres log file at all, even
with log_min_error_statement set to info.

In psql, I see the VACUUM VERBOSE output in the psql session itself,
but I need to log the output. I could spawn a psql session if necessary,
but ideally I'd just run VACUUM VERBOSE from JDBC and get the output
in the postgres log file.
