If you're running only a single query at a time (no multiple clients),
then this is pretty much the definition of a MySQL-friendly workload;
I'd have to say we are doing really well if we are only 50% slower.
Postgres doesn't have any performance advantages until you get into
complex queries or a significant amount of concurrency.

You could possibly get some improvement if you can re-use prepared plans
for the queries; but this will require some fooling with the client code
(I'm not sure if DBD::Pg even has support for it at all).
