not sure why you consider this a bug - but "user" is a reserved word in
PostgreSQL and the SQL-Standard (see
http://www.postgresql.org/docs/9.0/static/sql-keywords-appendix.html) so
you would have to quote the keyword like:

create table ftp ("user" varchar, password varchar);

in your code - but I would advise against using reserved words at all
because you will end up having to quote them all over the place in each
and every query.
