It's not necessary to use -W unless you are trying to debug something
that happens during the backend startup process. Even then, I wouldn't
make it a postmaster parameter, because that causes *all* started
backends to delay. Instead say export PGOPTIONS="-W n" on the client
side before you start psql, so the delay only applies to your backend
under test. See

did...)
