Modifying the client to re-set the password is actually something I
thought about. There are some technical unknowns (e.g. is
PQencryptPasswordConn accessible through ODBC?) and some organisational
difficulties (e.g. can we get the customers to upgrade to the newest
version?), but I guess in our case it would be doable. But in general
changing every to client to upgrade the password doesn't seem feasible.
Unless maybe you are proposing that libpq should do that? That might
work, but it probably also shouldn't do it by default.
That seems to me to be the fastest way to get the feature out to users. (JDBC would also need it.)
Then clients like psql, pgAdmin, etc would need to add those calls.
