The following bug has been logged on the website:
Bug reference: 18869
Logged by: Daniel Elishakov
Email address: dan-eli@mail.ru
PostgreSQL version: 17.4
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.
