Subject: DROP OWNED again
Date: Fri, 18 Nov 2005 16:54:30 -0300
Message-ID: <[email protected]> (raw)
People,
Here is the patch for DROP OWNED (finally!). This patch implements two
new commands, DROP OWNED and REASSIGN OWNED BY.
DROP OWNED drops the objects owned by any of a list of roles (in the
current database, of course). It also revokes all privileges that have
been granted to any of them. One must have privileges of all the
mentioned roles in order to be able to do this. (So a superuser can do
it for any role, and in the simple case a role can do it only to
itself.)
REASSIGN OWNED gives the objects away to some other role. It doesn't
touch grants. So if a role has been granted something and you want to
drop it but keep the objects, you must do REASSIGN OWNED and then DROP
OWNED. One must have all privileges of all the mentioned roles in
order to do this, including the receiving role.
The idea of all this is that if you want to drop a role, you first issue
a DROP ROLE, note all the databases on which it says it has dependences,
connect to each and issue REASSIGN OWNED and/or DROP OWNED as
appropiate, and finally issue DROP ROLE again. This eases dropping a
role (or that is the theory anyway).
The patch is missing regression tests. I will include them when I apply
it. I intend to apply it tomorrow or so, unless somebody has (strong?
Is the time when people "strongly objected" to things gone?) objections
to it.

<title>Description</title>
<para>
The <command>DROP OWNED</command> instructs the system to drop those
database objects owned by one of the given roles which reside on the
current database. All privileges granted to the given roles will also be
revoked.
</para>
<para>
If <literal>CASCADE</> is specified, <command>DROP OWNED</command>
will behave like a <command>DROP ... CASCADE</command> was issued
for each object, that is, objects dependent on the ones owned by the
given users will be dropped as well.
</para>
</refsect1>
<refsect1>
<title>Notes</title>
<para>
The <command>DROP OWNED</command> command is mostly used in preparation to
drop the roles. It may be necessary to issue the command in more than one
database.
</para>
<para>
Using the <literal>CASCADE</literal> option may make the command recurse to
objects owned by other users.
</para>
<para>
See the <command>REASSIGN OWNED</command> command for an alternative that
gives the objects away to another role.
</para>
</refsect1>
<refsect1>
<title>Compatibility</title>
<para>
The <command>DROP OWNED</command> statement is a
<productname>PostgreSQL</productname> extension.

<title>Description</title>
<para>
The <command>REASSIGN OWNED</command> instructs the system to change
the ownership of the database objects owned by one of the old_roles,
to new_role.
</para>
</refsect1>
<refsect1>
<title>Notes</title>
<para>
The <command>REASSIGN OWNED</command> command is mostly used in preparation to
drop the roles. See the <command>DROP OWNED</command> command for an
alternative that drops the objects.
</para>
<para>
The <command>REASSIGN OWNED</command> command does not affect the privileges
granted to the old_roles in objects not owned by them. Use
<command>DROP OWNED</command> to remove them.
</para>
</refsect1>
<refsect1>
<title>Compatibility</title>
<para>
The <command>REASSIGN OWNED</command> statement is a
<productname>PostgreSQL</productname> extension.

<title>Description</title>
<para>
The <command>DROP OWNED</command> instructs the system to drop those
database objects owned by one of the given roles which reside on the
current database. All privileges granted to the given roles will also be
revoked.
</para>
<para>
If <literal>CASCADE</> is specified, <command>DROP OWNED</command>
will behave like a <command>DROP ... CASCADE</command> was issued
for each object, that is, objects dependent on the ones owned by the
given users will be dropped as well.
</para>
</refsect1>
<refsect1>
<title>Notes</title>
<para>
The <command>DROP OWNED</command> command is mostly used in preparation to
drop the roles. It may be necessary to issue the command in more than one
database.
</para>
<para>
Using the <literal>CASCADE</literal> option may make the command recurse to
objects owned by other users.
</para>
<para>
See the <command>REASSIGN OWNED</command> command for an alternative that
gives the objects away to another role.
