Log Message:
-----------
Avoid redundant relation lock grabs during planning, and make sure
that we acquire a lock on relations added to the query due to inheritance.
Formerly, no such lock was held throughout planning, which meant that
a schema change could occur to invalidate the plan before it's even
been completed.
