postscreen has unique requirements, and I don't think they should
drive the choice of a Postfix default database (low read/write
latency, and either exclusive access or a lock-free architecture
such as LMDB which is based on multi-version concurrency control).
But, if LMDB is available as a package for all supported systems,
then a switch would be feasible, though painful because it is a
forced transition. We might just as well phase out the 'default
database type' and require that all commands and configurations
specifu an explcit database type.
