One, it now returns the previous hook. That way people don't have to dig
around in libpq-int.h for that information anymore. It previously
returned void, so there should be no incompatibilities.
Second, you cannot set the callback to NULL anymore. (Of course you can
still call it with NULL just to get the current hook.) The way libpq uses
the callback pointer, having a NULL there wasn't very healthy.

The following patch extends the COMMENT ON functionality to the
rest of the database objects beyond just tables, columns, and views. The
grammer of the COMMENT ON statement now looks like:
COMMENT ON [
[ DATABASE | INDEX | RULE | SEQUENCE | TABLE | TYPE | VIEW ] <objname>
|
COLUMN <relation>.<attribute> |
AGGREGATE <aggname> <aggtype> |
FUNCTION <funcname> (arg1, arg2, ...) |
OPERATOR <op> (leftoperand_typ rightoperand_typ) |
TRIGGER <triggername> ON relname>

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.
when an initdb-forcing change has been applied within a development cycle.
PG_VERSION serves this purpose for official releases, but we can't bump
the PG_VERSION number every time we make a change to the catalogs during
development. Instead, increase the catalog version number to warn other
developers that you've made an incompatible change. See my mail to
pghackers for more info.
fix recently applied to backend's lexer). I see that YY_USES_REJECT
still gets defined for this lexer, which means it's going to have trouble
parsing really long tokens. Not sure if it's worth doing anything about
that or not; I don't have the interest right now to understand why
ecpg's additions to the syntax cause this problem...
This patch fix a TODO list item.
* require SELECT DISTINCT target list to have all ORDER BY columns
example
ogawa=> select distinct x from t1 order by y;
ERROR: ORDER BY columns must appear in SELECT DISTINCT target list

boundary-condition bug in myinput() which caused flex scanner to fail
on tokens larger than a bufferload. Turns out flex doesn't want null-
terminated input ... and if it gives you a 1-character buffer, you'd
better supply a character, not a null, lest you be thought to be
reporting end of input.
proc_exit time. I discovered that if the frontend closes the connection
when you're inside a transaction block, there is nothing ensuring that
temp files go away ... I wonder whether proc_exit ought to try to do an
explicit transaction abort?
a generalized module 'tuplesort.c' that can sort either HeapTuples or
IndexTuples, and is not tied to execution of a Sort node. Clean up
memory leakages in sorting, and replace nbtsort.c's private implementation
of mergesorting with calls to tuplesort.c.
recycle storage within sort temp file on a block-by-block basis. This
reduces peak disk usage to essentially just the volume of data being
sorted, whereas it had been about 4x the data volume before.
