code is broken, but any small change in the output format might overrun
the buffer with the old size.

From Rod Taylor.

FOUND is set whenever a SELECT INTO returns > 0 rows, *or* when an
INSERT, UPDATE, or DELETE affects > 0 rows. We implemented the first
part of this behavior, but not the second.

I also improved the documentation on the various situations in which
FOUND can be set (excluding inside FOR loops, which I still need to
think about), and added some regression tests for this behavior.

It's also a necessity for an informational schema.  The catalog
(database) name is required in a number of places.

latent wrong-struct-type bugs and makes the coding style more uniform,
since the majority of places working with lists of column names were
already using Strings not Idents.  While at it, remove vestigial
support for Stream node type, and otherwise-unreferenced nodes.h entries
for T_TupleCount and T_BaseNode.
NB: full recompile is recommended due to changes of Node type numbers.
This shouldn't force an initdb though.

been missing forever; surprising it wasn't noticed before.  The other
additions are, um, sloppiness in certain recent feature additions.

when two equal() targetlist items were to be added to an ORDER BY or
DISTINCT list.  Although indeed this would make sorting fractionally
faster by sometimes saving a comparison, it confuses the heck out of
later stages of processing, because it makes it look like the user
wrote DISTINCT ON rather than DISTINCT.  Bug reported by joe@piscitella.com.

master and slave tables.

The -n and -N options were removed.  Quoting is now smart enough to
supply quotes if and only if necessary.

Numerical types are now printed without quotes, except in cases of
special values such as NaN.

Boolean values printed as true and false.

Most string literals now do not escape whitespace characters (newlines,
etc.) for portability.

SET SESSION AUTHORIZATION argument is a string literal, to follow SQL.

Made commands output by pg_dump use consistent spacing and indentation.

This patch is an updated version of the lock listing patch. I've made
the following changes:

    - write documentation
    - wrap the SRF in a view called 'pg_locks': all user-level
      access should be done through this view
    - re-diff against latest CVS

One thing I chose not to do is adapt the SRF to use the anonymous
composite type code from Joe Conway. I'll probably do that eventually,
but I'm not really convinced it's a significantly cleaner way to
bootstrap SRF builtins than the method this patch uses (of course, it
has other uses...)

Everytime if I do PQconsumeInput (when the backend channel gets
readable) I check for the return value. (0 == error) and generate a
notification manually, e.g. fixed string connection_closed) and pass it to the
TCL event queue. The only other thing I had to do is to comment out removing
all pending events in PgStopNotifyEventSource whenever the connection was
unexpectedly closed (so the manually generated event will not be deleted).

A broken backend connection triggers a notify event to the client (fixed
notification string "connection_closed") so proper action can be taken to switch
to another database server etc. Remember that this is event driven. If you have
applications, that have idle database connections most of the time, you'll get
immediate feedback of a dying server. Upon connection to the server issue a
pg_notify for notify event "connection_closed" and whenever the backend crashes
(which it does do in very very rare cases) you get an event driven recovery. (of
course the Tcl-Event loop has to be processed). Issuing a notification
"connection_closed" on a still working database could be used for switching to
another db-server (which I've actually impelemented right now).

constraints as such and hide the triggers.  pg_get_constraintdef()
function added to backend to support these.  From Rod Taylor, code
review and some editorialization by Tom Lane.
