Compiling warnings on old GCC

I came across the following compiling warnings on GCC (Red Hat 4.8.5-44)
4.8.5 with 'CFLAGS=-Og'

be-fsstubs.c: In function ‘be_lo_export’:
be-fsstubs.c:537:24: warning: ‘fd’ may be used uninitialized in this
function [-Wmaybe-uninitialized]
if (CloseTransientFile(fd) != 0)
^
In file included from trigger.c:14:0:
trigger.c: In function ‘ExecCallTriggerFunc’:
../../../src/include/postgres.h:314:2: warning: ‘result’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
return (Pointer) X;
^
trigger.c:2316:9: note: ‘result’ was declared here
Datum result;
^

I wonder if this is worth fixing, maybe by a trivial patch like
attached.

Thanks
Richard
