* Document/trigger/rule so changes to pg_shadow recreate pg_pwd

I did it with a trigger and it seems to work like a charm. The function
that already updates the file for create and alter user has been made a
built-in "SQL" function and a trigger is created at initdb time.

Comments around the pg_pwd updating function seem to be worried about
this
routine being called concurrently, but I really don't see a reason to
worry about this. Verify for yourself. I guess we never had a system
trigger before, so treat this with care, and feel free to adjust the
nomenclature as well.

* pg_dump should preserve primary key information

Also a couple of warnings removed.

Also, minor tweakage of tab completion, and I hope the output is flushed
on time now.

against the sources from one hour ago and contain all the portable and
up
to date stuff.

A few other CVS "householding" things you might want to take care of:

* Remove the src/bin/cleardbdir directory

* Remove the file src/bin/psql/sql_help.h from the repository, as it is
a derived file and is build by the release_prep.

them into the scripts dir. I also added a --list option to show already
installed languages.

This whole moving and renaming totally confused CVS and my checked out
copy got completely fried last night. When you apply the source patch,
please make sure that all the directories src/bin/{create|destroy}* as
well as vacuumdb, cleardbdir are gone and that all the scripts (7) are
in
scripts/.

Meanwhile I am still puzzled about what happened with the docs patch.
Because I don't know what you got now, the second attachment contains
the
files

ref/allfiles.sgml
ref/commands.sgml
ref/createlang.sgml
ref/droplang.sgml

rate
  it's better than what used to be there.

* Does proper SQL "host variable" substitution as pointed out by Andreas
  Zeugwetter (thanks): select * from :foo; Also some changes in how ':'
  and ';' are treated (escape with \ to send to backend). This does
_not_
  affect the '::' cast operator, but perhaps others that contain : or ;
  (but there are none right now).

* To show description with a <something> listing, append '?' to command
  name, e.g., \df?. This seemed to be the convenient and logical
solution.
  Or append a '+' to see more useless information, e.g., \df+.

* Fixed fflush()'ing bug pointed out by Jan during the regression test
  discussion.

* Added LastOid variable. This ought to take care of TODO item "Add a
  function to return the last inserted oid, for use in psql scripts"
  (under CLIENTS)
  E.g.,
insert into foo values(...);
insert into bar values(..., :LastOid);
\echo $LastOid

* \d command shows constraints, rules, and triggers defined on the table
  (in addition to indices)

* Various fixes, optimizations, corrections

* Documentation update as well


Note: This now requires snprintf(), which, if necessary, is taken from
src/backend/port. This is certainly a little weird, but it should
suffice
until a source tree cleanup is done.

Enjoy.

Make all system indexes unique.
Make all cache loads use system indexes.
Rename *rel to *relid in inheritance tables.
Rename cache names to be clearer.

(whoever thought world-writable files were a good default????).  Modify
the pg_pwd code so that pg_pwd is created with 600 permissions.  Modify
initdb so that permissions on a pre-existing PGDATA directory are not
blindly accepted: if the dir is already there, it does chmod go-rwx
to be sure that the permissions are OK and the dir actually is owned
by postgres.

descriptions enabled.

circumstances:
=> select * from foo\x\t\pset border 0 \p\g\\select * from bar;

Also the release prep update so the sql_help.h is generated before
packaging.

* Add use of 'const' for varibles in source tree
(which is misspelled, btw.)
I went through the front-end libpq code and did so. This affects in
particular the various accessor functions (such as PQdb() and
PQgetvalue()) as well as, by necessity, the internal helpers they use.

I have been really thorough in that regard, perhaps some people will find
it annoying that things like
char * foo = PQgetvalue(res, 0, 0)
will generate a warning. On the other hand it _should_ generate one. This
is no real compatibility break, although a few clients will have to be
fixed to suppress warnings. (Which again would be in the spirit of the
above TODO.)

In addition I replaced some int's by size_t's and removed some warnings
(and generated some new ones -- grmpf!). Also I rewrote PQoidStatus (so it
actually honors the const!) and supplied a new function PQoidValue that
returns a proper Oid type. This is only front-end stuff, none of the
communicaton stuff was touched.


The psql patch also adds some new consts to honor the new libpq situation,
as well as fixes a fatal condition that resulted when using the -V
(--version) option and there is no database listening.


So, to summarize, the psql you should definitely put in (with or without
the libpq). If you think I went too far with the const-mania in libpq, let
me know and I'll make adjustments. If you approve it, I will also update
the docs.

Fewer calls to nameout.

Better use of RelationGetRelationName.
