FormatMessage() (This should have been in 8.2.0, patched to 8.2.X and HEAD): I think this problem to be complex.... http://archives.postgresql.org/pgsql-hackers/2006-11/msg00042.php FormatMessage of windows cannot consider the encoding of the database. However, I should try the solution now. It is necessary to clear the problem. Multi character-code exists together in message and log. It doesn't consider the data base encoding that the user intended.... The user in multi-byte country can try this. http://inet.winpg.jp/~saito/pg_bug/MessageCheck.c That is, it is likely to become it in this manner.(Japanese) http://inet.winpg.jp/~saito/pg_bug/FormatMessage998.png Hiroshi Saito
