option settings. Sort out SIGHUP vs BACKEND -- there is no total ordering
here, so make explicit checks. Add comments explaining all of this.
Removed permissions check on SHOW command.
Add examine_subclass to the game, rename to SQL_inheritance to fit the
official data model better. Adjust documentation.
Standalone backend needs to reset all options before it starts. To
facilitate that, have IsUnderPostmaster be set by the postmaster itself,
don't wait for the magic -p switch.
Also make sure that all environment variables and argv's survive
init_ps_display(). Use strdup where necessary.
Have initdb make configuration files (postgresql.conf, pg_hba.conf) mode
0600 -- having configuration files is no fun if you can't edit them.

Clean up some funny business in the config file code.

That means you can now set your options in either or all of $PGDATA/configuration,
some postmaster option (--enable-fsync=off), or set a SET command. The list of
options is in backend/utils/misc/guc.c, documentation will be written post haste.
pg_options is gone, so is that pq_geqo config file. Also removed were backend -K,
-Q, and -T options (no longer applicable, although -d0 does the same as -Q).
Added to configure an --enable-syslog option.
changed all callers from TPRINTF to elog(DEBUG)

the src/include tree, so that -I backend is no longer necessary anywhere.
Also, clean up some bit rot in contrib tree.

logged queries to 1024, truncating longer queries. That is about half of
the size I need (I have a union that is 2K long). Can someone consider
bumping it to 4K or so? Patch attached...

Here's a patch to fix the " '.' not allowed in db path" problem I ran into.
I removed '.' from the set of illegial characters, but added backtick. I also
included an explicit test for attempting include a reference to a parent dir.
How that?

this is an old patch which I have already submitted and never seen
in the sources. It corrects the datatype oids used in some iterator
functions. This bug has been reported to me by many other people.
contrib-datetime.patch
some code contributed by Reiner Dassing <dassing@wettzell.ifag.de>
contrib-makefiles.patch
fixes all my contrib makefiles which don't work with some compilers,
as reported to me by another user.
contrib-miscutil.patch
an old patch for one of my old contribs.
contrib-string.patch
a small change to the c-like text output functions. Now the '{'
is escaped only at the beginning of the string to distinguish it
from arrays, and the '}' is no more escaped.
elog-lineno.patch
adds the current lineno of CopyFrom to elog messages. This is very
useful when you load a 1 million tuples table from an external file
and there is a bad value somehere. Currently you get an error message
but you can't know where is the bad data. The patch uses a variable
which was declared static in copy.c. The variable is now exported
and initialized to 0. It is always cleared at the end of the copy
or at the first elog message or when the copy is canceled.
I know this is very ugly but I can't find any better way of knowing
where the copy fails and I have this problem quite often.
plperl-makefile.patch
fixes a typo in a makefile, but the error must be elsewhere because
it is a file generated automatically. Please have a look.
tprintf-timestamp.patch
restores the original 2-digit year format, assuming that the two
century digits don't carry much information and that '000202' is
easier to read than 20000202. Being only a log file it shouldn't
break anything.
Please apply the patches before the next scheduled code freeze.
I also noticed that some of the contribs don't compile correcly. Should we
ask people to fix their code or rename their makefiles so that they are
ignored by the top makefile?

* Let unprivileged users change their own passwords.
* The password is now an Sconst in the parser, which better reflects its text datatype and also
forces users to quote them.
* If your password is NULL you won't be written to the password file, meaning you can't connect
until you have a password set up (if you use password authentication).

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.
|

Fewer calls to nameout.
Better use of RelationGetRelationName.

eliminating some wildly inconsistent coding in various parts of the
system. I set MAXPGPATH = 1024 in config.h.in. If anyone is really
convinced that there ought to be a configure-time test to set the
value, go right ahead ... but I think it's a waste of time.

* Buffer refcount cleanup (per my "progress report" to pghackers, 9/22).
* Add links to backend PROC structs to sinval's array of per-backend info,
and use these links for routines that need to check the state of all
backends (rather than the slow, complicated search of the ShmemIndex
hashtable that was used before). Add databaseOID to PROC structs.
* Use this to implement an interlock that prevents DESTROY DATABASE of
a database containing running backends. (It's a little tricky to prevent
a concurrently-starting backend from getting in there, since the new
backend is not able to lock anything at the time it tries to look up
its database in pg_database. My solution is to recheck that the DB is
OK at the end of InitPostgres. It may not be a 100% solution, but it's
a lot better than no interlock at all...)
* In ALTER TABLE RENAME, flush buffers for the relation before doing the
rename of the physical files, to ensure we don't get failures later from
mdblindwrt().
* Update TRUNCATE patch so that it actually compiles against current
sources :-(.
You should do "make clean all" after pulling these changes.

additional argument specifying the kind of lock to acquire/release (or
'NoLock' to do no lock processing). Ensure that all relations are locked
with some appropriate lock level before being examined --- this ensures
that relevant shared-inval messages have been processed and should prevent
problems caused by concurrent VACUUM. Fix several bugs having to do with
mismatched increment/decrement of relation ref count and mismatched
heap_open/close (which amounts to the same thing). A bogus ref count on
a relation doesn't matter much *unless* a SI Inval message happens to
arrive at the wrong time, which is probably why we got away with this
sloppiness for so long. Repair missing grab of AccessExclusiveLock in
DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi.
Recommend 'make clean all' after pulling this update; I modified the
Relation struct layout slightly.
Will post further discussion to pghackers list shortly.

This change seems necessary in conjunction with long queries, and it
cleans up some bogosity in connection with long EXPLAIN texts anyway.
Note that current libpq will accept any length error message (at least
until it runs out of memory); prior versions have a limit of 8K, but
will cleanly discard excess error text, so there shouldn't be any
big compatibility problems with old clients.

this one could be useful for people experiencing out-of-memory crashes while
executing queries which retrieve or use a very large number of tuples.
The problem happens when storage is allocated for functions results used in
a large query, for example:
select upper(name) from big_table;
select big_table.array[1] from big_table;
select count(upper(name)) from big_table;
This patch is a dirty hack that fixes the out-of-memory problem for the most
common cases, like the above ones. It is not the final solution for the
problem but it can work for some people, so I'm posting it.
The patch should be safe because all changes are under #ifdef. Furthermore
the feature can be enabled or disabled at runtime by the `free_tuple_memory'
options in the pg_options file. The option is disabled by default and must
be explicitly enabled at runtime to have any effect.
To enable the patch add the follwing line to Makefile.custom:
CUSTOM_COPT += -DFREE_TUPLE_MEMORY
To enable the option at runtime add the following line to pg_option:
free_tuple_memory=1

the gettimeofday doesn't compile under Linux with glibc2 because
the DST_NONE constant is no more defined. It seems that this code
(written by me) has always be wrong but for some reason working.

Get rid of a couple that no longer do anything (like -P).
