LGTM. I tested in this way:
```
% ls -l src/include/utils/guc_tables.inc.c
lrwxr-xr-x@ 1 chaol staff 43 Nov 3 13:27 src/include/utils/guc_tables.inc.c
-> ../../../src/backend/utils/guc_tables.inc.c
% find src/backend src/common src/port src/include \
\( -name '*.c' -o -name 'proctypelist.h' \) \
-print | grep guc_tables.inc.c
src/backend/utils/guc_tables.inc.c
src/include/utils/guc_tables.inc.c
% find src/backend src/common src/port src/include -type f \
\( -name '*.c' -o -name 'proctypelist.h' \) \
-print | grep guc_tables.inc.c
src/backend/utils/guc_tables.inc.c
```
Without -type f, find lists both the regular file and the symbolic link. With
-type f, it lists only the regular file, as expected.
