> * -Add getpid() function to backend

this only works against 7.3 or later databases; the pushups required
to do it without regprocedure/regtype/etc seem more trouble than they're
worth, considering that existing users aren't expecting pg_dump support
for this.

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

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

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/> ?

'tioga recipes', whatever those are -- Peter E. killed most
of it a couple days ago, but this patch removes the rest. Most
of it was #ifdef'ed out anyway.

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.

a few other things:

* Made all references to the pg_* tables absolute, by specifying
  the pg_catalog schema.

* Added SCHEMA as a create/delete completion option.

* Added SCHEMA completion as: SELECT nspname FROM
pg_catalog.pg_namespace
  WHERE substr(nspname,1,%d)='%s'

* Added completion of "INSERT INTO <table> (" with attribute names.

* Added completion of "INSERT INTO <table> (attribs)" with
  VALUES or SELECT

* Added limited locking completion: only for one table:
  "LOCK" and "LOCK TABLE" now both get a completion list of tables
  Complete with "IN" for LOCK [TABLE] <table>
  Complete LOCK [TABLE] <table> IN with a lock mode

* Added a very simple WHERE finisher that uses the previous word
  as a table lookup for attributes.

* Added quote support when parsing "previous words". In other words,
  hitting tab after INSERT INTO "foo bar baby"
  now does the right thing and recognizes "foo bar baby" as one word.

Letting tab-complete quote things that should be quoted seems to be
temporarily ifdef'ed out due to readline compatibility problems.
Can anyone elaborate on this?

deleted that had another row inserted/updated to its old
value during the same statement or other statements before the
integrity check for noaction would incorrectly error.  This
could happen in deferred constraints or due to triggers or
functions. It's effectively a reworking of the previous patch that
did a not exists to instead do a separate check.

we may as well use it in all our flex files.  Make all the flex files
have a consistent set of options.

three functions which exercise the tablefunc API.

show_all_settings()
   - returns the same information as SHOW ALL, but as a query result

normal_rand(int numvals, float8 mean, float8 stddev, int seed)
   - returns a set of normally distributed float8 values
   - This routine implements Algorithm P (Polar method for normal
     deviates) from Knuth's _The_Art_of_Computer_Programming_, Volume 2,
     3rd ed., pages 122-126. Knuth cites his source as "The polar
     method", G. E. P. Box, M. E. Muller, and G. Marsaglia,
     _Annals_Math,_Stat._ 29 (1958), 610-611.

crosstabN(text sql)
   - returns a set of row_name plus N category value columns
   - crosstab2(), crosstab3(), and crosstab4() are defined for you,
     but you can create additional crosstab functions per directions
     in the README.

Joe 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.

tutorial example too.

copied more places than I first thought it would.  This fixes a bug:
a couple of these places were neglecting to enforce USAGE access on
explicitly-referenced schemas.
