Fix failure of <command>ALTER TABLE ... ALTER COLUMN TYPE</command>

indexes using the altered columns were not processed correctly,
leading to strange failures during <command>ALTER TABLE</command>.

<para>
Fix mishandling of multi-column foreign keys when rebuilding a
foreign key constraint (Tom Lane)
</para>
<para>
<command>ALTER TABLE</command> could make an incorrect decision about
whether revalidation of a foreign key is necessary, if not all
columns of the key are of the same type. It seems likely that the
error would always have been in the conservative direction, that is
revalidating unnecessarily.

<para>
Prevent incorrect canonicalization of date ranges
with <literal>infinity</literal> endpoints (Laurenz Albe)
</para>
<para>
It's incorrect to try to convert an open range to a closed one or
vice versa by incrementing or decrementing the endpoint value, if
the endpoint is infinite; so leave the range alone in such cases.

Fix <application>pg_dump</application> to ensure that custom operator
classes are dumped in the right order (Tom Lane)
</para>
<para>
If a user-defined opclass is the subtype opclass of a user-defined
range type, related objects were dumped in the wrong order,
producing an unrestorable dump. (The underlying failure to handle
opclass dependencies might manifest in other cases too, but this is
the only known case.)
