Make sure it's clear that the prohibition on adding a column with a default
when the rowtype is used elsewhere is intentional, and be a bit more
explicit about the other cases where we perform this check.

It's full of backend-specific error reporting, so it's neither possible
nor necessary for this to be used from frontend code.

This isn't kosher, and doesn't play nicely with my recent changes to the
Makefile in this directory.

Remove the claim that ALTER TABLE .. SET DATA TYPE is the fastest way of
rewriting a table, since it no longer is.

This fixes make distprep, and seems more robust in other ways as well.
Some special handling is required because errcodes.txt is needed by
some stuff in src/port, but just by src/backend as is the case for the
other generated headers.

While I'm at it, fix a few other things that were overlooked in the
original patch.

Another case of <xref linkend> in the documentation that
builds INSTALL, which is not allowed.

In the hope of unbreaking the buildfarm

My commit ddfe26f6 of 2010-02-03 broke it.

src/pl/plpgsql/src/plerrcodes.h, src/include/utils/errcodes.h, and a
big chunk of errcodes.sgml are now automatically generated from a single
file, src/backend/utils/errcodes.txt.

Prior to 9.0, restartpoints never created, deleted, or recycled WAL
files, but now they can.  This code makes log_checkpoints treat
checkpoints and restartpoints symmetrically.  It also adjusts up
the documentation of the parameter to mention restartpoints.

This allows the language-specific try/catch construct to catch and
handle exceptions arising from SPI calls, matching the behavior of
other PLs.

As an additional bonus you no longer get all the ugly "unrecognized
error in PLy_spi_execute_query" errors.
