Feature request: Password prompt

[paulrobello]

I am using the postgres adapter so I am not sure if this is a request for the adapter or harlequin itself.

It would be a great feature to have an option to prompt for password so it does not have to be entered on the command line.

I like that idea. Might be both a harlequin feature for a new type of adapter option (I know Click supports prompt callbacks) and an adapter feature to add a password prompt option.
