effectively used to mean a default value that could also be spelled
out explicitly. (ACLs behave that way, and useconfig/datconfig
do too IIRC.)
It's a bit of a hack, but it saves table space and backend code ---
without this convention the default would have to be inserted "manually"
since we have no mechanism to supply defaults when C code is forming a
new catalog tuple.
I'm inclined to leave the code alone. But Alvaro is right that it'd be
good to point out the 'infinity' option in the CREATE USER and ALTER
USER man pages. (Doc patch please?)

join is defined as:
from_item [ NATURAL ] join_type from_item
[ ON join_condition | USING ( join_column_list ) ]
However, if the join_type is an INNER or OUTER join, an ON, USING, or
NATURAL clause *must* be specified (it's not optional, as that segment
of the docs suggest).
I'm not exactly sure what the best way to fix this is, so I've attached
a patch adding a FIXME comment to the relevant section of the SGML. If
anyone has any ideas on the proper way to outline join syntax, please
speak up.

Add ALTER SEQUENCE to modify min/max/increment/cache/cycle values
Also updated create sequence docs to mention NO MINVALUE, & NO MAXVALUE.
New Files:
doc/src/sgml/ref/alter_sequence.sgml
src/test/regress/expected/sequence.out
src/test/regress/sql/sequence.sql
ALTER SEQUENCE is NOT transactional. It behaves similarly to setval().
It matches the proposed SQL200N spec, as well as Oracle in most ways --
Oracle lacks RESTART WITH for some strange reason.

Envrironment and Files section, explained exactly what -w
does)
This is a patch which allows pg_ctl to make an intelligent
guess as to the proper port when running 'psql -l' to
determine if the database has started up (the -w flag).
The environment variable PGPORT is used. If that is not found,
it checks if a specific port has been set inside the postgresql.conf
file. If it is has not, it uses the port that Postgres was
compiled with.

utility statement (DeclareCursorStmt) with a SELECT query dangling from
it, rather than a SELECT query with a few unusual fields in it. Add
code to determine whether a planned query can safely be run backwards.
If DECLARE CURSOR specifies SCROLL, ensure that the plan can be run
backwards by adding a Materialize plan node if it can't. Without SCROLL,
you get an error if you try to fetch backwards from a cursor that can't
handle it. (There is still some discussion about what the exact
behavior should be, but this is necessary infrastructure in any case.)
Along the way, make EXPLAIN DECLARE CURSOR work.
- more work from the SGML police
- some grammar improvements: rewriting a paragraph or two, replacing
contractions where (IMHO) appropriate
- fix missing utility commands in lock mode docs
- improve CLUSTER, REINDEX, SET SESSION AUTHORIZATION ref pages

Yes, it should. (attached)
[ Backpatched to 7.3.X too.]

Ok, fair enough: a revised patch is attached that uses the '-n' short
option and the '--schema' long option.

restriction was debatable to begin with, but it has now become obvious
that it breaks forward-porting of user-defined types; contrib/lo being
the most salient example.
including:
- replacing all the appropriate usages of <citetitle>PostgreSQL
...</citetitle> with &cite-user;, &cite-admin;, and so on
- fix an omission in the EXECUTE documentation
- add some more text to the EXPLAIN documentation
- improve the PL/PgSQL RETURN NEXT documentation (more work to do here)
- minor markup fixes

beginning/end of cursor.
Have MOVE return 0/1 depending on cursor position.
Matches SQL spec.
Pass cursor counter from parser as a long rather than int.
Doc updates.
* Add schema, cast, and conversion backslash commands to psql
I had to create a new publically available function,
pg_conversion_is_visible, as it seemed to be missing from the catalogs.
This required me to do no small amount of hacking around in namespace.c
I have updated the \? help and sgml docs.
\dc - list conversions [PATTERN]
\dC - list casts
\dn list schemas
I didn't support patterns with casts as there's nothing obvious to match
against.
Catalog version incremented --- initdb required.

make VALUE a non-reserved word again, use less invasive method of passing
ConstraintTestValue into transformExpr, fix problems with nested constraint
testing, do correct thing with NULL result from a constraint expression,
remove memory leak. Domain checks still need much more work if we are going
to allow ALTER DOMAIN, however.
