I decided to go with the following because I think it
is easier to read:

continue;
It didn't occur to me so far to mention it but this could be replaced with:
if (rte->perminfoindex != 0)
and turn that condition into an Assert instead, like the loop over
range table in ExecCheckPermissions() does.
Hmmm, that might work, and save us a filter on rte->perminfoindex later
on (to filter out table partitions). Thanks for the tip!
I considered adding Assert(relkind == RELKIND_VIEW) in all places that
have the "rte->rtekind == RTE_SUBQUERY && OidIsValid(rte->relid)"
condition, but that seemed like an overkill, so only added one in the
#ifdef USE_ASSERT_CHECKING block in ExecCheckPermissions() that
f75cec4fff877 added.
This seems like a good place for the assert.
I added a comment above this Assert.
I'd like to push this tomorrow barring objections.
+1 for the new comment.
