problems with extensions compiling after upgrade to fc42 (and gcc15)

Hi

I found a problem with compilation of plpgsql_check when I upgraded my
fedora.

plpgsql_check cannot be compiled (against PostgreSQL 15-). The compilation
fails

rc/expr_walk.c:84:66: warning: passing argument 2 of ‘query_tree_walker’
from incompatible pointer type [-Wincompatible-pointer-types]
84 |
detect_dependency_walker,

^~~~~~~~~~~~~~~~~~~~~~~~

_Bool (*)(Node *, void *)
In file included from src/expr_walk.c:14:
/usr/local/pgsql/13/include/server/nodes/nodeFuncs.h:137:52: note: expected
‘_Bool (*)(void)’ but argument is of type ‘_Bool (*)(Node *, void *)’

| ~~~~~~~^~~~~~~~~~
src/expr_walk.c:43:1: note: ‘detect_dependency_walker’ declared here
43 | detect_dependency_walker(Node *node, void *context)
| ^~~~~~~~~~~~~~~~~~~~~~~~

It is strange, so the source code of Postgres is compiled without problems.

The workaround is pushing to Makefiie

override CFLAGS += -Wno-error=incompatible-pointer-types
