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-Q, and -T options (no longer applicable, although -d0 does the same as -Q).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)

        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?

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.
