1. this is the wrong forum for this question - here we discuss
postgresql developments, not usage
2. use a pgpass file, possibly with a PGPASSFILE environment setting as
well - see the docs for details. This works on all platforms and should
work with anything at all calling pg_dump.
3. In general, the only way to "fool" programs properly this way is to
use expect or some equivalent that uses ptys. In this case, it would be
overkill.
