If it happens only once and after that everything seems to be working then you can probably just forget about it. As this is happening only at boot, it looks like postfix starts connecting to mariadb before before mariadb is ready to accept connections. There could be some missing dependency in the startup scripts or it could be a dependency which the startup scripts cannot correctly manage (for example if maridb starts successfully but then there is a non zero time before when it starts and when it accepts connections).
