When compiling PG19 beta1 on Fedora 44 I got the following warning:


839/2360] Compiling C object src/backend/postgres_lib.a.p/optimizer_util_cl=
auses.c.o
../src/backend/optimizer/util/clauses.c: In function =91recheck_cast_functi=

es=92 may be used uninitialized [-Wmaybe-uninitialized]

This is still the same as reported in BUG 19485
