was created on a machine with alignment rules and floating-point format
similar to the current machine. Per recent discussion, this seems like
a good idea with the increasing prevalence of 32/64 bit environments.

argument as a 'regclass' value instead of a text string. The frontend
conversion of text string to pg_class OID is now encapsulated as an
implicitly-invocable coercion from text to regclass. This provides
backwards compatibility to the old behavior when the sequence argument
is explicitly typed as 'text'. When the argument is just an unadorned
literal string, it will be taken as 'regclass', which means that the
stored representation will be an OID. This solves longstanding problems
with renaming sequences that are referenced in default expressions, as
well as new-in-8.1 problems with renaming such sequences' schemas or
moving them to another schema. All per recent discussion.
Along the way, fix some rather serious problems in dbmirror's support
for mirroring sequence operations (int4 vs int8 confusion for instance).

the ProcessUtility case, resulting in an intratransaction memory leak
if a utility command actually did return any tuples, as reported by
Dmitry Karasik. Fix this and also make the behavior more consistent
for cases involving nested SPI operations and multiple query trees,
by ensuring that we store the state locally until it is ready to be
returned to the caller.

Also, make pg_total_relation_size include the size of the
TOAST index.

only the inner-side relation would be considered as potential equijoin clauses,
which is wrong because the condition doesn't necessarily hold above the point
of the outer join. Per test case from Kevin Grittner (bug#1916).

building contrib with USE_PGXS. To make it work all the way, the
pg_regress script would need to be included in the installation tree.

relocated after installation. We can't trust the installation paths
inserted into Makefile.global by configure, so instead we must get the
paths from pg_config. This requires extending pg_config to support all
the separately-configurable path names, but that was on TODO anyway.

outer relation is empty did not work, per test case from Patrick Welche.
It tried to use nodeHashjoin.c's high-level mechanisms for fetching an
outer-relation tuple, but that code expected the hash table to be filled
already. As patched, the code failed in corner cases such as having no
outer-relation tuples for the first hash batch. Revert and rewrite.

for int8 and related types. However we might be talking to a client
that has working int64; so pq_getmsgint64 really needs to check the
incoming value and throw an overflow error if we can't represent it
accurately.

"optimization". When we find a potentially useful joinclause, we
have to add all its other required_relids to the result, not only the
other clause_relids. They are different in the case of a joinclause
whose applicability has to be postponed due to outer join. We have
to include the extra rels because otherwise, after best_inner_indexscan
masks the join rels with index_outer_relids, it will always fail to
find the joinclause as applicable. Per report from Husam Tomeh.

in which invalid page data could be transiently written to disk by
concurrent bgwriter activity. There doesn't seem any risk of loss of
actual user data, but an empty page could possibly be left corrupt if a
crash occurs before the correct data gets written out. Pointed out by
Alvaro Herrera.

It uses existing macros instead of touching directly.

already changed initdb in a way that assumed it worked like this, seems
we'd better make it work like this.
