Check that with a different client encoding...

Btw something I found recently .. FreeBSD + PG 8.4.4 (default config) ->
CentOS 5.9 + PG 8.4.9 (default config) using bucardo fails to replicate
Umlauts(the error for me showed as 'Bad Byte in UTF8 Encoding').. I had
to patch bucardo to issue 'SET client_encoding = "latin1";' to both the
source and destination to get it to work.  It maybe an associated problem.
