length is less than original string length.

As I read it, the spec requires a non-null result in some cases where
one of the inputs is NULL: specifically, if the other endpoint of that
interval is between the endpoints of the other interval, then the result
is known TRUE despite the missing endpoint.  The spec could've been a
lot simpler if they did not intend this behavior.
I did not force an initdb for this change, but if you don't do one you'll
still see the old strict-function behavior.

if the transaction has already been committed ?

transformForUpdate does: it should recurse into subqueries.

It could be recursing into a sub-query where there was already a FOR
UPDATE clause.

work where we can (given that the executor only handles it at top level)
and generate an error where we can't.  Note that while the parser has
been allowing views to say SELECT FOR UPDATE for a few weeks now, that
hasn't actually worked until just now.

an error at end of transaction ... and I did *not* like it.  Reduce ERROR
to NOTICE so that this situation doesn't cause an infinite loop.

an error as we used to.  In an OUTER JOIN scenario, retrieving a null
CTID from one of the input relations is entirely expected.  We still
want to lock the input rows from the other relations, so just ignore
the null and keep going.

I believe this should fix the issue that Philip Warner
noticed about the check for unique constraints meeting the
referenced keys of a foreign key constraint allowing the
specification of a subset of a foreign key instead of
rejecting it.  I also added tests for a base case of
this to the foreign key and alter table tests and patches
for expected output.

report from Joel Burton.  Turns out that my simple idea of turning the
SELECT into a subquery does not interact well *at all* with the way the
rule rewriter works.  Really what we need to make INSERT ... SELECT work
cleanly is to decouple targetlists from rangetables: an INSERT ... SELECT
wants to have two levels of targetlist but only one rangetable.  No time
for that for 7.1, however, so I've inserted some ugly hacks to make the
rewriter know explicitly about the structure of INSERT ... SELECT queries.
Ugh :-(

about being given accurate references to referenced libraries ...

directories too, not only src and doc.

for portability.  Per discussion on pghackers around 9/16/00.

Allow some operator-like tokens to be used as function names.
Flesh out support for time, timetz, and interval operators
 and interactions.
Regression tests pass, but non-reference-platform horology test results
 will need to be updated.
