This used to be the case, but it's not anymore. You can run long-living queries, run pg_dump, etc on slaves.

Ah, that's really good news to hear. Seems it's time to upgrade. :)

Could you, please, provide a reference to a documentation or a changelog? Maybe I'm looking for a wrong keywords, but I can't find any mentions of such changes by myself.

Do you have a reference in which pg version this got fixed? We still pg_xlog_replay_pause() our slaves, it would be nice to drop that.
