Thanks for the fast answer. Is there any way to avoid that? I mean, in MS SQL Server, I do have "with no_lock" (that produces dirty reads)? Or the way to go is the transaction isolation level?

there's no actual overhead in a single statement read transaction like this. Postgres uses a novel approach to MVCC.
