77be5f9451 AdjustTimestampForTypmod does not work (at least not portably) on
-infinity and +infinity.  Put TIMESTAMP_NOT_FINITE guard into the routine,
instead of forgetting it at some call sites.  Fixes regression test
failures here.

3e1beda2cd Implement precision support for timestamp and time, both with and without
time zones.
SQL99 spec requires a default of zero (round to seconds) which is set
 in gram.y as typmod is set in the parse tree. We *could* change to a
 default of either 6 (for internal compatibility with previous versions)
 or 2 (for external compatibility with previous versions).
Evaluate entries in pg_proc wrt the iscachable attribute for timestamp and
 other date/time types. Try to recognize cases where side effects like the
 current time zone setting may have an effect on results to decide whether
 something is cachable or not.

f2c657375d Add CREATE OR REPLACE FUNCTION syntax to allow replacing a function
definition without changing the function's OID, thereby not breaking
rules, views, triggers, etc that depend on it.  From Gavin Sherry.

e5bbf19659 Extend pg_get_indexdef() to know about index predicates. Also, tweak
it to suppress index opclass output for opclasses that are the default
for their datatype; only non-default opclasses are shown explicitly.
This is expected to improve portability of the CREATE INDEX command
across future versions of Postgres --- we've changed index opclasses
too often in the past to think we won't do so again.

5999e78fc4 Another round of cleanups for dynahash.c (maybe it's finally clean of
portability issues).  Caller-visible data structures are now allocated
on MAXALIGN boundaries, allowing safe use of datatypes wider than 'long'.
Rejigger hash_create API so that caller specifies size of key and
total size of entry, not size of key and size of rest of entry.
This simplifies life considerably since each number is just a sizeof(),
and padding issues etc. are taken care of automatically.

f00da6d841 Allow the postmaster to accept changes in PGC_BACKEND GUC variables
from the config file, so that these changes will propagate to backends
started later.  Already-started backends continue to ignore changes

f9f258281e Create a GUC parameter max_files_per_process that is a configurable
upper limit on what we will believe from sysconf(_SC_OPEN_MAX).  The
default value is 1000, so that under ordinary conditions it won't
affect the behavior.  But on platforms where the kernel promises far
more than it can deliver, this can be used to prevent running out of
file descriptors.  See numerous past discussions, eg, pgsql-hackers
around 23-Dec-2000.

499abb0c0f Implement new 'lightweight lock manager' that's intermediate between
existing lock manager and spinlocks: it understands exclusive vs shared
lock but has few other fancy features.  Replace most uses of spinlocks
with lightweight locks.  All remaining uses of spinlocks have very short
lock hold times (a few dozen instructions), so tweak spinlock backoff
code to work efficiently given this assumption.  All per my proposal on
pghackers 26-Sep-01.

6f58115ddd Measure the current transaction time to milliseconds.
Define a new function, GetCurrentTransactionStartTimeUsec() to get the time
 to this precision.
Allow now() and timestamp 'now' to use this higher precision result so
 we now have fractional seconds in this "constant".
Add timestamp without time zone type.
Move previous timestamp type to timestamp with time zone.
Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss
 (note the "T" separating the day from hours information).
Remove 'current' from date/time types; convert to 'now' in input.
Separate time and timetz regression tests.
Separate timestamp and timestamptz regression test.

35b7601b04 Add an overall timeout on the client authentication cycle, so that
a hung client or lost connection can't indefinitely block a postmaster
child (not to mention the possibility of deliberate DoS attacks).
Timeout is controlled by new authentication_timeout GUC variable,
which I set to 60 seconds by default ... does that seem reasonable?

ae3129fd03 Quick-and-dirty fix for recursive plpgsql functions, per bug report from
Frank Miles 7-Sep-01.  This is really just sticking a finger in the dike.
Frank's case works now, but we still couldn't support a recursive function
returning a set.  Really need to restructure querytrees and execution
state so that the querytree is *read only*.  We've run into this over and
over and over again ... it has to happen sometime soon.

264f8f2b6c Install dynamically loadable modules into a private subdirectory
under libdir, for a cleaner separation in the installation layout
and compatibility with binary packaging standards.  Point backend's
default search location there.  The contrib modules are also
installed in the said location, giving them the benefit of the
default search path as well.  No changes in user interface
nevertheless.

Here's rev 2 of the bytea string support patch. Changes:

1. Added missing declaration for MatchBytea function
2. Added PQescapeBytea to fe-exec.c
3. Applies cleanly on cvs tip from this afternoon

I'm hoping that someone can review/approve/apply this before beta starts, so
I guess I'd vote (not that it counts for much) to delay beta a few days :-)

21a7fa8a6f It is not fixed and I doubt that it is working fine in current CVS. The
bugfix is in the attached patch. Please apply it. Thanks.

 Output must be:

test=# SELECT to_char(485, 'RN');
     to_char
-----------------
         CDLXXXV
(1 row)

test=# SELECT to_char(485, 'FMRN');
 to_char
---------
 CDLXXXV
(1 row)

test=# SELECT to_char(1000, 'RN');
     to_char
-----------------
               M
(1 row)


test=# SELECT to_char(7.2, '"Welcome to"9.9 "release! :-)"');
           to_char

 Welcome to 7.2 release! :-)

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).

 Forget it! A default client encoding must be set by actual database encoding...
Please apply the small attached patch that solve it better.

02b1a7fd51 Clean up some confusion about where and how to set whereToSendOutput.
We will no longer try to send elog messages to the client before we have
initialized backend libpq (oops); however, reporting bogus commandline
switches via elog does work now (not irrelevant, because of PGOPTIONS).
Fix problem with inappropriate sending of checkpoint-process messages
to stderr.
