Bug reference:      18869
Logged by:          Daniel Elishakov

Operating system:   ubuntu 20.04
Description:

If root is NULL, pointer clause can also be NULL and then dereferenced at
createplan.c:5104 at if (IsA(clause, OpExpr)). I guess there should be a
check for NULL.

root would never be null here, and neither would the clause.

In general, we are not terribly interested in "bug reports" generated
by unsupported static analysis.
