Description:

All versions 9.x.x Postgresql have a BUG. Its configured for 127.0.0.1 but
binds to all IP (0.0.0.0)!

In postgresql.conf:

listen_addresses = '127.0.0.1'

but in reality:

postgres.exe    TCP    0.0.0.0    5432                    and
postgres.exe    TCP    ::    5432

What's the trouble? Please fix this bug.
Sorry for my english.
