Sure but wouldn't that show up as more time spent in the server in the parser
and planner? I thought Tom was complaining that it was spending too much time
in the client not waiting on server responses.
I wonder if Postgres is being bitten by doing lots of extra round trips. Maybe
the MySQL driver detects when there are no placeholders and no parameters and
uses a different protocol method that only requires a single round trip? Or
given your example maybe it even notices no result is needed and doesn't even
wait for a response?
