Use off_t and size_t in pg_dump to handle file offset arithmetic correctly.

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.

cause SERIAL column declaration not to imply UNIQUE, so that this can be
done without creating an extra index.

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...)

constraints as such and hide the triggers. pg_get_constraintdef()
function added to backend to support these. From Rod Taylor, code

Thanks.
Attached is a patch against cvs tip as of 8:30 PM PST or so. Turned out
that even after fixing the failed hunks, there was a new spot in
bufmgr.c which needed to be fixed (related to temp relations;
RelationUpdateNumberOfBlocks). But thankfully the regression test code
caught it :-)

Chapter 1. libpq - C Library
1.3. Command Execution Functions
1.3.3. Escaping binary strings for inclusion in SQL queries
I found the line
"The result string length does not include the terminating zero byte of the result."
is not right.
The result string length does indeed include the terminating zero byte.

Okay, I've attached an updated patch with more information on
SQL_INHERITANCE and inheritance behavior in prior releases.

of this variable. I present the first cut here.
Currently the format for the file should be

to make a reasonable attempt at accounting for palloc overhead, not just
the requested size of each memory chunk. Since in many scenarios this
will make for a significant reduction in the amount of space acquired,
partially compensate by doubling the default value of SORT_MEM to 1Mb.

I sent the CLUSTER patch a few days ago and I think it was missed. I
append it again, this time including the regression test files. For the
committer, please note that you have to cvs add the files as they don't
exist. Maybe add to the parallel and serial schedules also, but I don't
know such stuff.
