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.

Shouldn't this be HeapTupleHeaderData and not HeapTupleData ?

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

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.

complaint about count('x') being broken, and improves consistency in
a few other respects too.

plan because there are no valid left-sided or right-sided join trees.
Accordingly, hoary sanity check needs an update.  Per report from

some concurrent changes Jan was making to the bufmgr. Here's an
updated version of the patch -- it should apply cleanly to CVS
HEAD and passes the regression tests.

This patch makes the following changes:

     - remove the UnlockAndReleaseBuffer() and UnlockAndWriteBuffer()
       macros, and replace uses of them with calls to the appropriate
       functions.

     - remove a bunch of #ifdef BMTRACE code: it is ugly & broken
       (i.e. it doesn't compile)

     - make BufferReplace() return a bool, not an int

     - cleanup some logic in bufmgr.c; should be functionality
       equivalent to the previous code, just cleaner now

     - remove the BM_PRIVATE flag as it is unused

     - improve a few comments, etc.

example from the RESET reference page because it seemed completely
redundant.
