the system's getopt_long().  The previous coding was the result of a sloppy
discussion that failed to draw this distinction.  The result was that PG
programs don't handle options as users of that platform expect.  Per
gripe from Chuck McDevitt.

Although this is a pre-existing bug, I'm not backpatching since I think we
could do with a bit of beta testing before concluding this is really OK.

mode while callers hold pointers to in-memory tuples.  I reported this for
the case of nodeWindowAgg's primary scan tuple, but inspection of the code
shows that all of the calls in nodeWindowAgg and nodeCtescan are at risk.
For the moment, fix it with a rather brute-force approach of copying
whenever one of the at-risk callers requests a tuple.  Later we might
think of some sort of reference-count approach to reduce tuple copying.

In the backend, I changed only a handful of exemplary or important-looking
instances to make use of the plural support; there is probably more work
there.  For the rest of the source, this should cover all relevant cases.

step to occur in its scan).  This avoids storing useless column values when
the outer relation's tuples are written to temporary batch files.

This is the core infrastructure needed to support the soon-to-appear
contrib/btree_gin module.  The APIs are still upward compatible with the
definitions used in 8.3 and before, although *not* with the previous 8.4devel
function definitions.

catversion bump for changes in pg_proc entries (although these are just
cosmetic, since GIN doesn't actually look at the function signature before
calling it...)

not global variables of anonymous enum types.  This didn't actually hurt
much because most linkers will just merge the duplicated definitions ...
but some will complain.  Per bug #4731 from Ceriel Jacobs.

Backpatch to 8.1 --- the declarations don't exist before that.
