Massive overhaul of pg_dump: make use of dependency information from

Browse Source 
pg_depend to determine a safe dump order.  Defaults and check constraints
can be emitted either as part of a table or domain definition, or
separately if that's needed to break a dependency loop.  Lots of old
half-baked code for controlling dump order removed.

<listitem>
<para>
Rearrange items by object type (this occurs after the sorting
specified by <option>-N</option> or <option>-o</option>, if
given). The rearrangement is intended to give the best possible
restore performance.

<para>
When none of <option>-N</option>, <option>-o</option>, and
<option>-r</> appear, <application>pg_restore</application> restores
items in the order they appear in the dump's table of contents,
or in the order they appear in the <REPLACEABLE
CLASS="PARAMETER">list-file</REPLACEABLE> if <option>-L</> is
given. The combination of <option>-o</> and <option>-r</>
duplicates the sorting done by <application>pg_dump</application>
before creating the dump's table of contents,
and so it is normally unnecessary to specify it.
