<para>
Ignore the <literal>CONCURRENTLY</literal> option when performing an
index creation, drop, or rebuild on a temporary table (Michael
Paquier, Heikki Linnakangas, Andres Freund)
</para>
<para>
This avoids strange failures if the temporary table has
an <literal>ON COMMIT</literal> action. There is no benefit in
using <literal>CONCURRENTLY</literal> for a temporary table anyway,
since other sessions cannot access the table, making the extra
processing pointless.

Avoid stack overflow in <literal>information_schema</literal> views

A self-referential view can't work; it will always result in
infinite recursion. We handled that situation correctly when
trying to execute the view, but not when inquiring whether it is
automatically updatable.
