code review by Tom Lane.  Remaining issues: functions that take or
return tuple types are likely to break if one drops (or adds!)
a column in the table defining the type.  Need to think about what
to do here.

Along the way: some code review for recent COPY changes; mark system
columns attnotnull = true where appropriate, per discussion a month ago.

attstattarget to indicate 'use the default'.  The default is now a GUC
variable default_statistics_target, and so may be changed on the fly.  Along
the way we gain the ability to have pg_dump dump the per-column statistics
target when it's not the default.  Patch by Neil Conway, with some kibitzing
from Tom Lane.

All of the internal tags are of the latter.

The other thing I noticed is that most of the quick examples in the file
use a para and synopsis.  Is there a reason we're not using <example/> ?

The attached patch completes the following TODO item:

    * Generate failure on short COPY lines rather than pad NULLs

I also restructed a lot of the existing COPY code, did some code
review on the column list patch sent in by Brent Verner a little
while ago, and added some regression tests. I also added an
explicit check (and resultant error) for extra data before
the end-of-line.

Neil Conway

changes mentioned above, and also adds a new function to the tablefunc
API. The tablefunc API change adds the following function:

* Oid foidGetTypeId(Oid foid) - Get a function's typeid given the
* function Oid. Use this together with TypeGetTupleDesc() to get a
* TupleDesc which is derived from the function's declared return type.

In the next post I'll send the contrib/tablefunc patch, which
illustrates the usage of this new function. Also attached is a doc patch
for this change. The doc patch also adds a function that I failed to
document previously.

contains descriptions of every single system table.  Update 'complex'
tutorial example too.

< * Allow logging of query durations

documentation (xindex.sgml should be rewritten), need to teach pg_dump
about it, need to update contrib modules that currently build pg_opclass
entries by hand.  Original patch by Bill Studenmund, grammar adjustments
and general update for 7.3 by Tom Lane.

< 	o ALTER TABLE ADD COLUMN column SET DEFAULT should fill existing
> 	o ALTER TABLE ALTER COLUMN column SET DEFAULT should fill existing

Add information about environment variables.

Some makefile simplifications.

pg_language.lancompiler
pg_operator.oprprec
pg_operator.oprisleft
pg_proc.proimplicit
pg_proc.probyte_pct
pg_proc.properbyte_cpu
pg_proc.propercall_cpu
pg_proc.prooutin_ratio
pg_shadow.usetrace
pg_type.typprtlen
pg_type.typreceive
pg_type.typsend

Attempts to use the obsoleted attributes of pg_operator or pg_proc
in the CREATE commands will be greeted by a warning.  For pg_type,
there is no warning (yet) because pg_dump scripts still contain these
attributes.

Also remove new but already obsolete spellings
isVolatile, isStable, isImmutable in WITH clause.  (Use new syntax
instead.)
