* src/backend/rewrite/: rewriteHandler.c (REL7_3_STABLE),
rewriteHandler.c (REL7_4_STABLE), rewriteHandler.c: Revert
ill-starred change of 13-Feb-02: it appeared to fix a problem of
incorrect permissions checking, but in fact disabled most all
permissions checks for view updates. This corrects problems
reported by Sergey Yatskevich among others, at the cost of
re-introducing the problem previously reported by Tim Burgess.
However, since we'd lived with that problem for quite awhile
without knowing it, we can live with it awhile longer until a
proper fix can be made in 7.5.

permission-checking bug reported by Tim Burgess 10-Feb-03 (this
time for sure...). Rather than relying on the query context of a
rangetable entry to identify what permissions it wants checked,
store a full AclMode mask in each RTE, and check exactly those
bits. This allows an RTE specifying, say, INSERT privilege on a
view to be copied into a derived UPDATE query without changing
meaning. Per recent discussion thread. initdb forced due to
change of stored rule representation.
