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
-Wdeclaration-after-statement -Werror=vla -Wendif-labels
-Wmissing-format-attribute -Wimplicit-fallthrough=3
-Wcast-function-type -Wshadow=compatible-local -Wformat-security
-fno-strict-aliasing -fwrapv -fexcess-precision=standard
-Wno-format-truncation -Wno-stringop-truncation -ggdb3 -O3
CFLAGS_SL = -fPIC

The compiler version is:
gcc --version
gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
