* Includes tab completion. It's not magic, but it's very cool. At any

rate
  it's better than what used to be there.

* Does proper SQL "host variable" substitution as pointed out by Andreas
  Zeugwetter (thanks): select * from :foo; Also some changes in how ':'
  and ';' are treated (escape with \ to send to backend). This does
_not_
  affect the '::' cast operator, but perhaps others that contain : or ;
  (but there are none right now).

* To show description with a <something> listing, append '?' to command
  name, e.g., \df?. This seemed to be the convenient and logical
solution.
  Or append a '+' to see more useless information, e.g., \df+.

* Fixed fflush()'ing bug pointed out by Jan during the regression test
  discussion.

* Added LastOid variable. This ought to take care of TODO item "Add a
  function to return the last inserted oid, for use in psql scripts"
  (under CLIENTS)
  E.g.,
insert into foo values(...);
insert into bar values(..., :LastOid);
\echo $LastOid

* \d command shows constraints, rules, and triggers defined on the table
  (in addition to indices)

* Various fixes, optimizations, corrections

* Documentation update as well


Note: This now requires snprintf(), which, if necessary, is taken from
src/backend/port. This is certainly a little weird, but it should
suffice
until a source tree cleanup is done.

Enjoy.
