Sorry for the inconvenience. I would like to write docs for the
multi-byte support in PostgreSQL for the next release.

I am not sure the binary being compiled with mb.

Sounds strange. I assume you use "set client encoding to 'LATIN1'" or
something like that. It is just a query for psql, since psql doesn't
parse the contents of the query, it should be possible for non-mb psql
to send the query.

Anyway, to make sure that you are using mb enabled psql, start
postmaster with "-d 3" flag to get debug output (turn off -
S. otherwise debug out will not appear). You should get lots of
messages including following portions:

query: select getdatabaseencoding()
ProcessQuery
CommitTransactionCommand
StartTransactionCommand
query: SET client_encoding = 'LATIN1'
ProcessUtility: SET client_encoding = 'LATIN1'

If not, you gotta into trouble. You need to build mb enabled psql on
PC by yourself. Unfortunately I cannot make it for you, since I have
very little knowledges about Windows. Maybe Hiroki Kataoka have some
suggestions...
