accidentally, but I had broken it while extending the code to allow
materialize-mode functions to be called in select lists.  Add a regression
test case so it doesn't get broken again.  Per gripe from Greg Davidson.

in cursors.  This has always been the case, but given the lack of user
complaints about it, I'm not going to bother back-patching this.

node starts from the same place as the first scan did.  This avoids surprising
behavior of scrollable and WITH HOLD cursors, as seen in Mark Kirkwood's bug
report of yesterday.

It's not entirely clear whether a rescan should be forced to drop out of the
syncscan mode, but for the moment I left the code behaving the same on that
point.  Any change there would only be a performance and not a correctness
issue, anyway.

Back-patch to 8.3, since the unstable behavior was created by the syncscan
patch.

Back-patch to 7.4, because it's broken all the way back.

In particular, always show 0 for the date type instead of null, and show
6 (the default) for time, timestamp, and interval without a declared
precision.  This is now in fuller conformance with the SQL standard.

Also clarify the documentation about this.

more consistent with other cases, by having an unlabeled integer field
be treated as a number of minutes or seconds respectively.  These cases
are outside the spec (which insists on full "dd hh:mm" or "dd hh:mm:ss"
input respectively), so it's not much help to us in deciding what to do.
But with this change, it's uniformly the case that an unlabeled integer
will be considered as being a number of the interval's rightmost field.
The change also takes us back to the 8.3 behavior of throwing error
for certain ambiguous inputs such as INTERVAL '1 2' DAY TO MINUTE.
Per recent discussion.

Sergey Burladyan, there are at least some dank corners of libxml2 that
assume this behavior, even though their published documentation suggests
they shouldn't.

This is only really a live problem in 8.3, but the code is still there
for possible debugging use in HEAD, so patch both branches.

will throw an error, rather than possibly allowing someone to synthesize
a manual call to an internal-accepting function.  As of CVS HEAD and existing
releases, all such functions are either STRICT or careful about null inputs,
so there is no current security issue here.  But it seems like a good idea
to lock this down to protect against future mistakes.

In passing, similarly lock down trigger_in, language_handler_in, opaque_in,
and shell_in.  These are not believed to present any security risk, but
there's still no good reason to allow nulls of these types to be created.
I left the polymorphic pseudotypes (anyelement etc) alone, since a null
of one of those types doesn't seem to be a problem --- the worst you can
say about it is that it doesn't have an underlying non-polymorphic type.

If we were to make this change during normal development, we'd just
automatically bump catversion for a pg_proc.h change.  But since this doesn't
create a compatibility risk and isn't believed to be fixing a live bug, it
seems better not to force a catversion bump in late beta.

"array_agg_finalfn(null)".  We should modify pg_proc entries to prevent this
query from being accepted, but let's just make the function itself secure too.

create an ABI break between 8.3 and 8.4.  It is still just a wrapper around
the built-in current_query() function, but at a different implementation
level.  Per my proposal.

also backpatched to 8.3

The original implementation of the 3-argument form of get_raw_page() risked
core dumps if the 8.3 SQL function definition was mistakenly used with the
8.4 module, which is entirely likely after a dump-and-reload upgrade.  To
protect 8.4 beta testers against upgrade problems, add a check on PG_NARGS.

In passing, fix missed additions to the uninstall script, and polish the

the <@ and @> operators.  These are not in fact equivalent to the built-in
anyarray operators of the same names, because they have different behavior for
empty arrays, namely they don't think empty arrays are contained in anything.
That is mathematically wrong, no doubt, but until we can persuade GIN indexes
to implement the mathematical definition we should probably not change this.
Another reason for not changing it now is that we can't yet ensure the
opclasses will be updated correctly in a dump-and-reload upgrade.  Per
recent discussions.
