This one should work much better than the one I sent in previously. The
functionality is the same, but the patch was missing one file resulting
in
the compilation failing. The docs also received a minor fix.

PQconnectStart
PQconnectPoll
PQresetStart
PQresetPoll
PQsetenvStart
PQsetenvPoll
PQsetenvAbort
and brings into the published interface
PQsetenv.
The first four are asynchronous analogues of PQconnectdb and PQreset -
they allow an application to connect to the DB without blocking on
remote I/O.
The PQsetenv functions perform an environment negotiation with the
server.
Internal to libpq, pqReadReady and pqWriteReady have been made available
across the library (they were previously static functions inside
fe-misc.c). A lot of internal rearrangement has been necessary to
support these changes.
The API documentation has been updated also.
Caveats:
o The Windows code does not default to using non-blocking sockets,
since I have no documentation: Define WIN32_NON_BLOCKING_CONNECTIONS to
do that.
o The SSL code still blocks.

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.

Make all system indexes unique.
Make all cache loads use system indexes.
Rename *rel to *relid in inheritance tables.
Rename cache names to be clearer.
Move around a few other keywords which were not in the right category.
DEC and SESSION_USER are not yet committed to gram.y,
since I'm in the middle of working on JOIN syntax too.
