add --without-tk option to disable Tk.  We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X.  Also make sure that libpq is up to date for
libpgtcl.  Remove executable bits from pgaccess.sh, but add it to pgaccess.

omission of alias_clause for a subselect.

complaints about ungrouped variables.  This is for consistency with
behavior elsewhere, notably the fact that the relname is reported as
an alias in these same complaints.  Also, it'll work with subselect-
in-FROM where old code didn't.

sublinks when outer query contained aggregates but no GROUP clause.

        - rename ichar() to chr() (discussed with Tom)

        - add docs for oracle compatible routines:

                btrim()
                ascii()
                chr()
                repeat()

        - fix bug with timezone in to_char()

        - all to_char() variants return NULL instead textin("")
          if it's needful.

 The contrib/odbc is without changes and contains same routines as main
tree ... because I not sure how plans are Thomas with this :-)

This effectively one line patch should fix the fact that
foreign key definitions in create table were erroring if
a primary key was defined.  I was using the columns
list to get the columns of the table for comparison, but
it got reused as a temporary list inside the primary key
stuff.

that's actually useful, robust, consistent.

Better plan to generate aclocal.m4 as well: use m4 include directives,

query representation.  Note that GEQO_RELS setting is now interpreted
as the number of top-level items in the FROM list, not necessarily the
number of relations in the query.  This seems appropriate since we are
only doing join-path searching over the top-level items.

There is still no effective difference but it will kick in once setuid

revise ODBC "installation instructions"; update some other outdated

ie, consider only the columns coming from the JOIN clause's sub-clauses.
Also detect attempts to reference columns belonging to other tables
(which would still be possible using an explicitly-qualified name).
I'm not sure this implements the spec's semantics 100% accurately, but
at least it gives plausible behavior.

DESTDIR=/else/where' and prepends the value of DESTDIR to the full
installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows
users to install the package into a location different from the one that
was configured and hard-coded into various scripts, e.g., for creating
binary packages.

DESTDIR is in many cases preferrable over `make install
prefix=/else/where' because

a) `prefix' affects the path that is hard-coded into the files, which can
lead to a `make install prefix=xxx' (as done by the regression test
driver) corrupting the files in the source tree with wrong paths.

b) it doesn't work at all if a directory was overridden to not depend on
`prefix', e.g., --sysconfdir=/etc.

(Updating the regression test driver to use DESTDIR is a separate
undertaking.)

can still work, per recent discussion on pghackers.  Correct some bugs
in ILIKE implementation.

- Use symbols for tests on relkind (ie. use RELKIND_VIEW, not 'v')
- Fix bug in support for -b option (== --blobs).
- Dump views as views (using 'create view').
- Remove 'isViewRule' since we check the relkind when getting tables.
- Now uses temp table 'pgdump_oid' rather than 'pg_dump_oid' (errors otherwise).
- Added extra param for specifying handling of OID=0 and which typename to output.
- Fixed bug in SQL scanner when SQL contained braces. (in rules)
- Use format_type function wherever possible

 regression tests for specific types, and move a few others to the
 cross-type "horology" test.
Rearrange the test order slightly, and move the abstime test to the
 "parallel safe" area.
Hand-patch the results for "1947" and for "solaris", so those may not
 be exactly correct.
