PGPASSWORD is passed down to psql as an environmental variable, it is
visible as part of psql's environment for the entire run of psql.
Whatever the calling script does later doesn't remove that window of
There is no intention of removing PGPASSWORD, because it is safe and
useful *on platforms that do not expose other processes' environment
variables*. But it is deprecated and will remain so, because there
are too many platforms where this is not true.

If .pgpass is properly protected, I do not see why you think it is
