Hi, I'm seeing a compiler warning with CFLAGS -O3 but not with -O2.

In file included from dbcommands.c:20:
dbcommands.c: In function ‘createdb’:
../../../src/include/postgres.h:104:16: warning: ‘src_hasloginevt’ may
be used uninitialized in this function [-Wmaybe-uninitialized]
  104 |         return (Datum) (X ? 1 : 0);
      |                ^~~~~~~~~~~~~~~~~~~
dbcommands.c:683:25: note: ‘src_hasloginevt’ was declared here
  683 |         bool            src_hasloginevt;
      |                         ^~~~~~~~~~~~~~~

The configure command I used is ./configure --prefix=$PWD/inst/
CFLAGS="-ggdb3 -O3" > install.log && make -j 8 install > install.log
2>&1 &:

CONFIGURE =  '--prefix=/home/ubuntu/postgres/inst/' 'CFLAGS=-ggdb3 -O3'
CC = gcc
CPPFLAGS = -D_GNU_SOURCE
CFLAGS = -Wall -Wmissing-prototypes -Wpointer-arith

CFLAGS_SL = -fPIC

The compiler version is:
