Peter Eisentraut c0d4d5473a Make the world somewhat safe for (not from) DELETE FROM pg_shadow;
Assign the fixed user id 1 to the user created by initdb.
A stand-alone backend will always set the user id to 1.
(Consequently, the name of that user is no longer important.)

In stand-alone mode, the user id 1 will have implicit superuser
status, to allow repairs even if there are no users defined.

Print a warning message when starting in stand-alone mode when no
users are defined.

Disallow dropping the current user and session user.

Granting/revoking superuser status also grants/revokes usecatupd.
(Previously, it would never grant it back.  This could lead to "deadlocks".)

CREATE USER and CREATE GROUP will start allocating user ids at 100
(unless explicitly specified), to prevent accidental creation of a
superuser (plus some room for future extensions).

Bruce Momjian 1834987fb6 I've attached the fixed version of the patch below. After the
discussion on pgsql-hackers (especially the frightening memory dump in
<12273.999562219@sss.pgh.pa.us>), we decided that it is best not to
use identifiers from an untrusted source at all.  Therefore, all
claims of the suitability of PQescapeString() for identifiers have
been removed.

Bruce Momjian bd9b32803b Here is my much-promised patch to let people add UNIQUE constraints after
table creation time.  Big deal you say - but this patch is the basis of the
next thing which is adding PRIMARY KEYs after table creation time.  (Which
is currently impossible without twiddling catalogs)

Rundown
-------

* I have made the makeObjectName function of analyze.c non-static, and
exported it in analyze.h

* I have included analyze.h and defrem.h into command.c, to support
makingObjectNames and creating indices

* I removed the 'case CONSTR_PRIMARY' clause so that it properly fails and
says you can't add primary keys, rather than just doing nothing and
reporting nothing!!!

* I have modified the docs.

Algorithm
---------

* If name specified is null, search for a new valid constraint name.  I'm
not sure if I should "lock" my generated name somehow tho - should I open
the relation before doing this step?

* Open relation in access exclusive mode

* Check that the constraint does not already exist

* Define the new index

* Warn if they're doubling up on an existing index

Tom Lane 17c03b30b0 Revert treatment of NOTIFY in rules to its pre-7.1 behavior: notify will
occur unconditionally, even if the rule should otherwise execute
conditionally.  This is more useful than giving an error, even though it's
not truly the correct behavior.  Per today's pghackers discussion.

See attached revised patch. (I'm sure the configure.in stuff can be done
right/better, I'm just not enough of a autoconf guru to know what to
change it to.)

Bruce Momjian 2a34134b6c - new to_char(interval, text)
- new millisecond (ms) and microsecond (us) support
 - more robus parsing from string - used is separator checking for
   non-exact formats like to_date('2001-9-1', 'YYYY-MM-DD')
 - SGML docs are included

Tom Lane 6c91eef7b7 Fix handling of pg_type.typdefault per bug report from Dave Blasby.
If there's anyone out there who's actually using datatype-defined
default values, this will be an incompatible change in behavior ...
but the old behavior was so broken that I doubt anyone was using it.

it wasn't entirely appropriate.

figures out their man system.

Tom Lane 2589735da0 Replace implementation of pg_log as a relation accessed through the
buffer manager with 'pg_clog', a specialized access method modeled
on pg_xlog.  This simplifies startup (don't need to play games to
open pg_log; among other things, OverrideTransactionSystem goes away),
should improve performance a little, and opens the door to recycling
commit log space by removing no-longer-needed segments of the commit
log.  Actual recycling is not there yet, but I felt I should commit
this part separately since it'd still be useful if we chose not to
do transaction ID wraparound.

Tom Lane f933766ba7 Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in
pgsql-hackers.  pg_opclass now has a row for each opclass supported by each
index AM, not a row for each opclass name.  This allows pg_opclass to show
directly whether an AM supports an opclass, and furthermore makes it possible
to store additional information about an opclass that might be AM-dependent.
pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we
previously expected the user to remember to provide in CREATE INDEX commands.
Lossiness is no longer an index-level property, but is associated with the
use of a particular operator in a particular index opclass.

Along the way, IndexSupportInitialize now uses the syscaches to retrieve
pg_amop and pg_amproc entries.  I find this reduces backend launch time by
about ten percent, at the cost of a couple more special cases in catcache.c's
IndexScanOK.

Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane.

initdb forced.

Tom Lane d4f4b971a4 Sequences are now based on int8, not int4, arithmetic. SERIAL pseudo-type
has an alias SERIAL4 and a sister SERIAL8.  SERIAL8 is just the same
except the created column is type int8 not int4.
initdb forced.  Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences.  (Which is
not out of the question, but I don't wanna do it.)
