for GRANT/REVOKE is now just that, not "CHANGE".
On the way, migrate some of the aclitem internal representation away from
the parser and build a real parse tree instead. Also add some 'const'
qualifiers.

appropriate pin-count manipulation, and instead use ReleaseAndReadBuffer.
Make use of the fact that the passed-in buffer (if there is one) must
be pinned to avoid grabbing the bufmgr spinlock when we are able to
return this same buffer. Eliminate unnecessary 'previous tuple' and
'next tuple' fields of HeapScanDesc and IndexScanDesc, thereby removing
a whole lot of bookkeeping from heap_getnext() and related routines.

that not many people actually use libpq on Win32; I have found another bug. Some
functions that are defined in libpq-fe.h aren't exported in the DLL version of
the library. I have added them to src/interfaces/libpq/libpqdll.def. The new
complete file is attached.

checkpoint's redo pointer, not its undo pointer, per discussion in
pghackers a few days ago. No point in hanging onto undo information
until we have the ability to do something with it --- and this solves
a rather large problem with log space for long-running transactions.
Also, change all calls of write() to detect the case where write
returned a count less than requested, but failed to set errno.
Presume that this situation indicates ENOSPC, and give the appropriate
error message, rather than a random message associated with the previous
value of errno.

copy PUBLIC access rights into each newly created ACL entry. Instead
treat each ACL entry as independent flags. Also clean up some ugliness
in acl.h API.

WHERE (a = 1 or a = 2) and b = 42
and an index on (a,b), include the clause b = 42 in the indexquals
generated for each arm of the OR clause. Essentially this is an index-
driven conversion from CNF to DNF. Implementation is a bit klugy, but
better than not exploiting the extra quals at all ...

of costsize.c routines to pass Query root, so that costsize can figure
more things out by itself and not be so dependent on its callers to tell
it everything it needs to know. Use selectivity of hash or merge clause
to estimate number of tuples processed internally in these joins
(this is more useful than it would've been before, since eqjoinsel is
somewhat more accurate than before).

conditional rules (rules with WHERE clauses). We cannot support these
since there's noplace to hang a condition on a utility statement.
We caught the other case (attempt to attach a condition at rewrite time)
awhile ago, but this one escaped notice until now.

(vs. at the end of a normal sort). This ensures that explicit sorts
yield the same ordering as a btree index scan. To be really sure that
that equivalence holds, we use the btree entries in pg_amop to decide
whether we are looking at a '<' or '>' operator. For a sort operator
that has no btree association, we put the nulls at the front if the
operator is named '>' ... pretty grotty, but it does the right thing in
simple ASC and DESC cases, and at least there's no possibility of getting
a different answer depending on the plan type chosen.

Use --enable-nls to turn it on; see installation instructions for details.
See developer's guide how to make use of it in programs and how to add
translations.
psql sources have been almost fully prepared and an incomplete German
translation has been provided. In the backend, only elog() calls are
currently translatable, and the provided German translation file is more
of a placeholder.

given values that compare as unordered, make sure we reply that they
are equal, which is better than giving an arbitrary answer --- at least
it doesn't depend on which one is passed as which arg.

the jdbc driver to ignore the encoding reported by the database when
multibyte isn't enabled and use the JVM default in that case.
