The thing is trying to report some error or other, and it discovers that the error text is badly encoded according to the current database encoding, and it tries to report that, only *that* error text is badly encoded too, so it tries to report that, getting another error, etc, until the error recovery stack overflows. The hope of getting rid of this scenario is one reason why we locked down encoding/locale combinations in 8.3, so I'm disappointed that you're still able to make it happen. You didn't say what settings you are using though. Could we see show lc_messages; show lc_ctype; show server_encoding; show client_encoding; regards, tom lane
