Can not running postinstall

[thang86]

When I follow install traffic OPs
[root@localhost ~]# /opt/traffic_ops/install/bin/postinstall
postinstall requires the postgres user to have superuser access to postgresql. Aborting.

but when i bypass check
root@localhost ~]# su - postgres psql -w -c 'show is_superuser'
su: invalid option -- 'w'
Try 'su --help' for more information.

and i test
[postgres@localhost ~]$ psql -w -c 'show is_superuser'
psql: error: fe_sendauth: no password supplied

You are using su improperly, consult man su.

Your PostgreSQL setup does not allow for the postgres user to authenticate without a password, consult the PostgreSQL documentation.

This command inculde postintall script

# make sure installed with proper permissions
umask 022

if [[ ! $(su - postgres psql -w -c 'show is_superuser' </dev/null 2>/dev/null) =~ 'on' ]]; then
        echo >&2 "postinstall requires the postgres user to have superuser access to postgresql. Aborting."
        exit 1
fi

and document ats for traffic ops have command :

su - postgres -c '/usr/pgsql-13/bin/initdb -A md5 -W' #-W forces the user to provide a superuser (postgres) password

This conflict command and script included /opt/traffic_ops/install/bin/postinstall
