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.

bit on the indexes.
I also attach clusterdb and clusterdb.sgml; both of them are blatant
rips of vacuumdb and vacuumdb.sgml, but get the job done. Please review
them, as I'm probably making a lot of mistakes with SGML and I can't
compile it here.
vacuumdb itself is not very comfortable to use when the databases have
passwords, because it has to connect once for each table (I can probably
make it connect only once for each database; should I?). Because of
this I added a mention of PGPASSWORDFILE in the documentation, but I
don't know if that is the correct place for that.

functionality of the command is basically identical to that of
BEGIN; it just accepts a few extra options (only one of which
PostgreSQL currently implements), and is standards-compliant.
The patch includes a simple regression test and documentation.
[ Regression tests removed, per Peter.]

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.
extension to create binary compatible casts. Includes dependency tracking
as well.
pg_proc.proimplicit is now defunct, but will be removed in a separate
commit.
pg_dump provides a migration path from the previous scheme to declare
casts. Dumping binary compatible casts is currently impossible, though.
A new pg_hba.conf column, USER
Allow specifiction of lists of users separated by commas
Allow group names specified by +
Allow include files containing lists of users specified by @
Allow lists of databases, and database files
Allow samegroup in database column to match group name matching dbname
Removal of secondary password files
Remove pg_passwd utility
Lots of code cleanup in user.c and hba.c
New data/global/pg_pwd format
New data/global/pg_group file
- domain.patch -> source patch against pgsql in cvs
- drop_domain.sgml and create_domain.sgml -> New doc/src/sgml/ref docs
- dominfo.txt -> basic domain related queries I used for testing
[ ADDED TO /doc]
Enables domains of array elements -> CREATE DOMAIN dom int4[3][2];
Uses a typbasetype column to describe the origin of the domain.
Copies data to attnotnull rather than processing in execMain().
Some documentation differences from earlier.
If this is approved, I'll start working on pg_dump, and a \dD <domain>
option in psql, and regression tests. I don't really feel like doing
those until the system table structure settles for pg_type.
CHECKS when added, will also be copied to to the table attributes. FK
Constraints (if I ever figure out how) will be done similarly. Both
will lbe handled by MergeDomainAttributes() which is called shortly
before MergeAttributes().

a separate statement (though it can still be invoked as part of VACUUM, too).
pg_statistic redesigned to be more flexible about what statistics are
stored. ANALYZE now collects a list of several of the most common values,
not just one, plus a histogram (not just the min and max values). Random
sampling is used to make the process reasonably fast even on very large
tables. The number of values and histogram bins collected is now
user-settable via an ALTER TABLE command.
There is more still to do; the new stats are not being used everywhere
they could be in the planner. But the remaining changes for this project
should be localized, and the behavior is already better than before.
A not-very-related change is that sorting now makes use of btree comparison
routines if it can find one, rather than invoking '<' twice.
Make version.sgml the central place for updating version numbers in the
documentation. Document titles now contain the version number of the
release they belong to.
filelist.sgml is the central (and only) place to declare system entities
(i.e., sgml files). No longer a need to declare them in each document
header.
There is no longer any need to maintain duplicate chapter lists in
postgres.sgml and user/admin/etc.sgml, everything is build from the same
sources. Some parameter entities allow for different text to be included
when the integrated or a single doc set is generated, which eliminates the
problems that had caused this to fail in the past.
Add some chapters on new topics.
Change to referencing OASIS/Docbook v3.1 rather than Davenport/Docbook v3.0
Grepped for and fixed apparent tag mangling from emacs
"Normalize" operation. Should be the last of those.
Add an appendix with more details on date/time attributes and handling.
Update most references to Postgres version numbers to 6.5,
*except* for the porting list which will require a report
from a successful installation to be updated.
