Postfix - MySQLi package no longer exists/is needed
I think due to a new update to postfix, it is no longer possible to use MySQLi for postfix’s access to its database.

postfix-mysqli does not exist in the Alpine repos (edge, main/testing)
I don’t know if this is an upstream bug or something, because mysqli used to work with the postfix-mysql package installed.
