You need to fix up your data. My guess is that what you have stored isn't really UTF-8 but something else (maybe one of the LATINn family). If so, adjusting the "SET client_encoding" line in the dump file and trying again should help. PG is certainly moving in the direction of more rather than less encoding checking, so this is something you gotta deal with. regards, tom lane
