       <para>
        These clauses determine whether a role is allowed to log in;
        that is, whether the role can be given as the initial session
        authorization name during client connection.  A role having
        the <literal>LOGIN</literal> attribute can be thought of as a user.
        Roles without this attribute are useful for managing database
        privileges, but are not users in the usual sense of the word.
        If not specified,
        <literal>NOLOGIN</literal> is the default, except when
        <command>CREATE ROLE</command> is invoked through its alternative spelling
        <link linkend="sql-createuser"><command>CREATE USER</command></link>.

      <listitem>
       <para>
        These clauses determine whether a role is a replication role.  A role
        must have this attribute (or be a superuser) in order to be able to
        connect to the server in replication mode (physical or logical
        replication) and in order to be able to create or drop replication
        slots.
        A role having the <literal>REPLICATION</literal> attribute is a very
        highly privileged role, and should only be used on roles actually
        used for replication. If not specified,
        <literal>NOREPLICATION</literal> is the default.
        Only superuser roles or roles with <literal>REPLICATION</literal>
        can specify <literal>REPLICATION</literal>.

      <listitem>
       <para>
        These clauses determine whether a role bypasses every row-level
        security (RLS) policy.  <literal>NOBYPASSRLS</literal> is the default.
        Only superuser roles or roles with <literal>BYPASSRLS</literal>
        can specify <literal>BYPASSRLS</literal>.

       <para>
        Note that pg_dump will set <literal>row_security</literal> to
        <literal>OFF</literal> by default, to ensure all contents of a table are
        dumped out.  If the user running pg_dump does not have appropriate
        permissions, an error will be returned.  However, superusers and the
        owner of the table being dumped always bypass RLS.

      <listitem>
       <para>
        If role can log in, this specifies how many concurrent connections
        the role can make.  -1 (the default) means no limit. Note that only
        normal connections are counted towards this limit. Neither prepared
        transactions nor background worker connections are counted towards
        this limit.

        Sets the role's password.  (A password is only of use for
        roles having the <literal>LOGIN</literal> attribute, but you
        can nonetheless define one for roles without it.)  If you do
        not plan to use password authentication you can omit this
        option.  If no password is specified, the password will be set
        to null and password authentication will always fail for that
        user.  A null password can optionally be written explicitly as
        <literal>PASSWORD NULL</literal>.
