PostgreSQL 8.3 is end-of-life so it shouldn't be our default anymore. The problem with changing the default PostgreSQL is that it breaks NixOS installations that have PostgreSQL enabled without specifying an explicit PostgreSQL version, because PostgreSQL does not do automatic schema migration if the major version changes. Thus, it's always a good idea to specify the desired major version explicitly: services.postgresql.package = pkgs.postgresql92; (In fact, maybe we should remove the default value for services.postgresql.package.)
