Posting an updated set of patches.
The only update is to include an improved, but only temporary, fix to
the query rewriter hasModifyingCTE issue (I separately posted a patch
for this but Tom Lane concluded that the issue is more complex than
initially thought, and no easy fix could be confidently attempted at
this point in time, so nothing ended up getting pushed - the issue
needs further investigation at another time).
See also comment in patch 0001.
