pretty much any query that has invalid utf8 byte code in it won't be
shown in the logs. the particular problem was with an adserver tool
(openX) that tried to insert iso-encoded data with umlauts (äüö) into an
utf8 database.
for example it tried to insert the geolocation "Zürich" during a ad
request logging which failed with:
" ERROR: invalid byte sequence for encoding "UTF8": 0xFC"
without showing the actual query.
maybe its by design (to not insert badly encoded characters into the
utf8 encoded logs)? nevertheless to debug those faulty programm/codes,
it would help to see what query provokes the error...

humm... don't know. pretty much standard out of the box pgsql
installation, the postresql.conf settings are defaults.
