* User management commands no longer user pg_exec_query_dest -> more robust

* Let unprivileged users change their own passwords.

* The password is now an Sconst in the parser, which better reflects its text datatype and also
forces users to quote them.

* If your password is NULL you won't be written to the password file, meaning you can't connect
until you have a password set up (if you use password authentication).

* When you drop a user that owns a database you get an error. The database is not gone.

<fileumask> is the umask(2) setting to use while creating an output file.
This should usually be more liberal than the backend's normal 077 umask,
but not always (in particular, "pg_pwd" should be written with 077!).
Up through version 6.5, <fileumask> was always 000, which was foolhardy.
When loading in the text format from an input stream (as opposed to
a file), recognize a "." on a line by itself as EOF. Also recognize
a stream EOF. When unloading in the text format to an output stream,
