What is meant is "The SQL standard allows an implementation to implement
stricter behavior than required by the standard; it only defines the things
that are *not* allowed to happen at a certain isolation level. So it is for
example fine for PostgreSQL not to allow dirty reads in READ UNCOMMITTED
isolation level."
Perhaps this could be rewritten to be clearer; it is indeed easy to
misunderstand that sentence.
