Use <xref linkend="SQL-CREATEUSER" endterm="SQL-CREATEUSER-title">
to add new users, and <xref linkend="SQL-ALTERUSER"
endterm="SQL-ALTERUSER-title"> to change a user's attributes.
<productname>PostgreSQL</productname> includes a program <xref
linkend="APP-DROPUSER" endterm="APP-DROPUSER-title"> that has the
same functionality as this command (in fact, it calls this command)
but can be run from the command shell.

<title>Compatibility</title>
<para>
The <command>DROP USER</command> statement is a
<productname>PostgreSQL</productname> extension. The SQL standard
leaves the definition of users to the implementation.
