a626b78c89 Clean up backend-exit-time cleanup behavior. Use on_shmem_exit callbacks
to ensure that we have released buffer refcounts and so forth, rather than
putting ad-hoc operations before (some of the calls to) proc_exit.  Add
commentary to discourage future hackers from repeating that mistake.

 Again thanks Kovacs, you found really designing bug, that appear
if anyone write bad format template to "number" version of to_char()
(as you with 'DD').

new transaction is not started

ea166f1146 Planner speedup hacking. Avoid saving useless pathkeys, so that path
comparison does not consider paths different when they differ only in
uninteresting aspects of sort order.  (We had a special case of this
consideration for indexscans already, but generalize it to apply to
ordered join paths too.)  Be stricter about what is a canonical pathkey
to allow faster pathkey comparison.  Cache canonical pathkeys and
dispersion stats for left and right sides of a RestrictInfo's clause,
to avoid repeated computation.  Total speedup will depend on number of
tables in a query, but I see about 4x speedup of planning phase for
a sample seven-table query.

468a970409 Change StoreCatalogInheritance() to work from a list of parent relation
OIDs rather than names.  Aside from being simpler and faster, this way
doesn't blow up in the face of 'create temp table foo () inherits (foo)'.
Which is a rather odd thing to do, but it seems some people want to.

17b843d677 Cache eval cost of qualification expressions in RestrictInfo nodes to
avoid repeated evaluations in cost_qual_eval().  This turns out to save
a useful fraction of planning time.  No change to external representation
of RestrictInfo --- although that node type doesn't appear in stored
rules anyway.

36da236eb3 In 'Joins between classes' in Section 5 of the tutorial we have, in
the first paragraph:

    As an example, say we wish to find all the records that
    are in the  temperature  range  of  other records. In
    effect, we need to compare the temp_lo and temp_hi
    attributes of each EMP instance to the temp_lo and
    temp_hi  attributes of all other EMP instances.

I believe that EMP should read WEATHER, as the example query that
follows joins WEATHER to itself.

EMP is often used in Oracle examples.

Regards,
Graham
