replace(string, from, to)
   -- replaces all occurrences of "from" in "string" to "to"
split(string, fldsep, column)
   -- splits "string" on "fldsep" and returns "column" number piece
to_hex(int32_num) & to_hex(int64_num)
   -- takes integer number and returns as hex string

Okay, libpq++ is moved to GBorg, and all traces of it have been removed
from the core repository ... I haven't *moved* the libpq++ files out of the
tree, mainly as we want to keep them in place for past branches ...

Peter, I think I've covered all the files I need, and re-ran autoconf to make
sure the configure file is in place properly ...

with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

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

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

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.

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.

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.
