With no specifics as to what he was doing, it's impossible to evaluate
whether the complaint is valid or not. I don't say he lied about the
times he observed, but there's no way to tell if it's a stupid query
design, failure to configure/tune the database properly, or a genuine
Postgres performance issue --- much less whether any such issue has
been fixed later.
I would translate the complaint as follows: "I know about SQL Server
and I can't be bothered to learn about Postgres". Pretty much a
self-fulfilling prophecy, eh?
