The patch combining and reordering was as suggested.

BEFORE:
v41-0001 Euler's main patch
v41-0002 Tab-complete
v41-0003 ExprState cache
v41-0004 OR/AND
v41-0005 Validation walker
v41-0006 new/old tuple updates

AFTER:
v42-0001 main patch <== v41-0001 + v41-0003 + v41-0004
v42-0002 validation walker <== v41-0005
v42-0003 new/old tuple updates <== v41-0006
v42-0004 tab-complete and pgdump <== v41-0002 (plus pgdump code from v41-0001)

~

Please note,  I did not remove the describe.c changes from the
v42-0001 patch at this time. I left this as-is because I felt the
ability for psql \d+ or \dRp+ etc to display the current row-filter is
*essential* functionality to be able to test and debug the 0001 patch
properly.
