a shared library, not just when installing it.

unfortunate considering that several subdirectory makefiles were counting
on it to do so...

Add detail on exact interpretation of "concatenated date"
 for various lengths.

with expression_tree_walker-based code.  The former failed to cope with
expressions containing SubLinks, and the latter returned TRUE for both
SubLinks and Aggrefs (cut-and-paste bug?).  There is a lot more scope for
using expression_tree_walker in this module, but I'll restrain myself
until the 6.6 split occurs from touching not-demonstrably-broken code.

sure if they are all fixed, because rewriter is now the stumbling block,
but at least some cases work that did not work before.

SubLink nodes after all ...

 aclchk.c: heap_close() is not called after calling heap_openr().

is parse_aggs.c.  This fixes its failure to cope with (at least) CaseExpr
and ArrayRef nodes, which is the reason why both of these fail in 6.5:
select coalesce(f1,0) from int4_tbl group by f1;
ERROR:  Illegal use of aggregates or non-group column in target list
select sentence.words[0] from sentence group by sentence.words[0];
ERROR:  Illegal use of aggregates or non-group column in target list
The array case still fails, but at least it's not parse_agg's fault
anymore ... considering that we now support CASE officially, I think
it's important to fix the first example ...

will gradually replace all of the boilerplate tree-walk-recursion code that
currently exists in O(N) slightly different forms in N subroutines.
I've had it with adding missing cases to these subroutines...

functions, in order to work around oversight in 6.5 release: rtree
index functions haven't got any.  Mea culpa ...

Did not check the function declarations as carefully as the other parts,
 though all of the function names *do* match up with D&D.
