Per Neil Conway.

evaluating a set-valued function.  This fixes some additional problems
with rescanning partially-evaluated SRFs.

shut down cleanly if the plan node is ReScanned before the SRFs are run
to completion.  This fixes the problem for SQL-language functions, but
still need work on functions using the SRF_XXX() macros.

was integrated into ecpg_informix.h, the other ones go into their own
subdirectory that is automatically considered by the embedded preprocessor
when in Informix mode.

users. :)

Shouldn't this be HeapTupleHeaderData and not HeapTupleData ?

(Of course, from a costing perspective these shouldn't be very different but ...)

where a joinclause is redundant with a restriction clause.  Original coding
believed this was impossible and didn't need to be checked for, but that
was a thinko ...

not discriminate against system columns, since we support constraints on
system columns, and in fact constraints on OID are moderately useful.

does not affect UNKNOWN-type literals or Params.  This fixes the recent
complaint about count('x') being broken, and improves consistency in
a few other respects too.

a join in its subselect.  In this situation we *must* build a bushy
plan because there are no valid left-sided or right-sided join trees.
Accordingly, hoary sanity check needs an update.  Per report from
Alessandro Depase.
