* 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.REL7_0_PATCHES

<command>ALTER GROUP</command> is used to change add users to a group or |

remove them from a group. Only database superusers can use this command. |

Adding a user to a group does not create the user. Similarly, removing |

a user from a group does not drop the user itself. |
