Fix a pg_dump output ordering problem introduced in 8.3 by the addition of
array types for composite types. Although pg_dump understood it wasn't
supposed to dump these array types as separate objects, it must include
them in the dependency ordering analysis, and it was improperly assigning them
the same relatively-high sort priority as regular types. This resulted in
effectively moving composite types and tables up to that same high priority,
which broke any ordering requirements that weren't explicitly enforced by
dependencies. In particular user-defined operator classes, which should come
out before tables, failed to do so. Per report from Brendan Jurd.
In passing, also fix an ill-considered decision to give text search objects
the same sort priority as functions and operators --- the sort result looks
a lot nicer if different object types are kept separate. The recent

A couple further reloptions improvements, per KaiGai Kohei: add a validation
function to the string type and add a couple of macros for string handling.
In passing, fix an off-by-one bug of mine.

Create a third option named "partition" for constraint_exclusion, and make it
the default. This setting enables constraint exclusion checks only for
appendrel members (ie, inheritance children and UNION ALL arms), which are
the cases in which constraint exclusion is most likely to be useful. Avoiding
the overhead for simple queries that are unlikely to benefit should bring
the cost down to the point where this is a reasonable default setting.
Per today's discussion.
