(It does not + affect privileges assigned to already-existing objects.) Currently, + only the privileges for schemas, tables (including views and foreign + tables), sequences, functions, and types (including domains) can be + altered. For this command, functions include aggregates and procedures. + The words <code class="literal">FUNCTIONS</code> and <code class="literal">ROUTINES</code> are + equivalent in this command. (<code class="literal">ROUTINES</code> is preferred + going forward as the standard term for functions and procedures taken + together. In earlier PostgreSQL releases, only the + word <code class="literal">FUNCTIONS</code> was allowed. It is not possible to set + default privileges for functions and procedures separately.) + </p><p> + You can change default privileges only for objects that will be created by + yourself or by roles that you are a member of. The privileges can be set + globally (i.e., for all objects created in the current database), + or just for objects created in specified schemas. + </p><p> + As explained in <a class="xref" href="ddl-priv.html" title="5.7. Privileges">Section 5.7</a>, + the default privileges for any object type normally grant all grantable + permissions to the object owner, and may grant some privileges to + <code class="literal">PUBLIC</code> as well. However, this behavior can be changed by + altering the global default privileges with + <code class="command">ALTER DEFAULT PRIVILEGES</code>. + </p><p> + Default privileges that are specified per-schema are added to whatever + the global default privileges are for the particular object type. + This means you cannot revoke privileges per-schema if they are granted + globally (either by default, or according to a previous <code class="command">ALTER + DEFAULT PRIVILEGES</code> command that did not specify a schema). + Per-schema <code class="literal">REVOKE</code> is only useful to reverse the + effects of a previous per-schema <code class="literal">GRANT</code>. + </p><div class="refsect2" id="id-1.9.3.8.5.6"><h3>Parameters</h3><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>target_role</code></em></span></dt><dd><p> + The name of an existing role of which the current role is a member. + Default access privileges are not inherited, so member roles + must use <code class="command">SET ROLE</code> to access these privileges, + or <code class="command">ALTER DEFAULT PRIVILEGES</code> must be run for + each member role.
