Hello Marina. I just reviewed your patch. It applied cleanly at my current master (commit d6a3dbe14f98d867b2fc3faeb99d2d3c2a48ca67).Also, it worked as described in email. Since it's a clarification in an error message, I think the documentation is fine.
I played a bit with "make check", creating a database in my native language (pt_BR), testing with some data and everything worked as expected.
