What happens when you run the following:

PGPASS="$(mktemp)"
. /usr/share/ovirt-engine/bin/engine-prolog.sh
PASSWORD="$(sed 's;\(["\$]\);\\\1;g' << __EOF__
${ENGINE_DB_PASSWORD}
__EOF__
)"
cat > "${PGPASS}" << __EOF__
${ENGINE_DB_HOST}:${ENGINE_DB_PORT}:${ENGINE_DB_DATABASE}:${ENGINE_DB_USER}:${PASSWORD}
__EOF__
PGPASSFILE="${PGPASS}"  psql -h "${ENGINE_DB_HOST}" -p
"${ENGINE_DB_PORT}" -U "${ENGINE_DB_USER}" -d "${ENGINE_DB_DATABASE}"
-c 'select 1'
rm "${PGPASS}"
