Fix breakage of GIN support for varchar[] and cidr[] that I introduced in the

pg_amproc entries for text[] and inet[] respectively.  However, binary
compatibility of the underlying types does not make two array types binary
compatible (since they must differ in the header field that gives the element

Rewrite make_outerjoininfo's construction of min_lefthand and min_righthand
sets for outer joins, in the light of bug #3588 and additional thought and
experimentation.  The original methodology was fatally flawed for nests of
more than two outer joins: it got the relationships between adjacent joins
right, but didn't always come to the right conclusions about whether a join
could be interchanged with one two or more levels below it.  This was largely
caused by a mistaken idea that we should use the min_lefthand + min_righthand
sets of a sub-join as the minimum left or right input set of an upper join
when we conclude that the sub-join can't commute with the upper one.  If
there's a still-lower join that the sub-join *can* commute with, this method
led us to think that that one could commute with the topmost join; which it
can't.  Another problem (not directly connected to bug #3588) was that
make_outerjoininfo's processing-order-dependent method for enforcing outer
join identity #3 didn't work right: if we decided that join A could safely
commute with lower join B, we dropped all information about sub-joins under B
that join A could perhaps not safely commute with, because we removed B's
entire min_righthand from A's.

To fix, make an explicit computation of all inner join combinations that occur
below an outer join, and add to that the full syntactic relsets of any lower
outer joins that we determine it can't commute with.  This method gives much
more direct enforcement of the outer join rearrangement identities, and it
turns out not to cost a lot of additional bookkeeping.

Fix a couple of misbehaviors rooted in the fact that the default creation
namespace isn't necessarily first in the search path (there could be implicit

test=# create table pg_class (f1 int primary key);

You'd expect these commands to create the requested objects in s1, since
names beginning with pg_ aren't supposed to be reserved anymore.  What is
happening is that we create the requested base table and then execute
additional commands (here, CREATE RULE or CREATE INDEX), and that code is
passed the same RangeVar that was in the original command.  Since that
RangeVar has schemaname = NULL, the secondary commands think they should do a
path search, and that means they find system catalogs that are implicitly in
front of s1 in the search path.

This is perilously close to being a security hole: if the secondary command
failed to apply a permission check then it'd be possible for unprivileged
users to make schema modifications to system catalogs.  But as far as I can
find, there is no code path in which a check doesn't occur.  Which makes it
just a weird corner-case bug for people who are silly enough to want to
name their tables the same as a system catalog.

The relevant code has changed quite a bit since 8.2, which means this patch
wouldn't work as-is in the back branches.  Since it's a corner case no one

Fix brain fade in DefineIndex(): it was continuing to access the table's
relcache entry after having heap_close'd it.  This could lead to misbehavior
if a relcache flush wiped out the cache entry meanwhile.  In 8.2 there is a
very real risk of CREATE INDEX CONCURRENTLY using the wrong relid for locking
and waiting purposes.  I think the bug is only cosmetic in 8.0 and 8.1,
because their transgression is limited to using RelationGetRelationName(rel)
in an ereport message immediately after heap_close, and there's no way (except
with special debugging options) for a cache flush to occur in that interval.
