I've been reading up on the use of the value and have notice a

the list.
The postconf(5) page and TLS_README file indicate:
"Specify a database type that supports enumeration, such as
btree or sdbm; there is no need to support concurrent access."
The official postfix.org online documentation is updated
frequently and is correct for the current version of postfix.
The online docs also usually indicate which version of
postfix it applies to when behavior changes.
Where as information from "The Book of Postfix" states:
"Session key caching requires concurrent write access to the
key database. In Postfix, only the SDBM database type supports
this. All TLS-enabled Postfix installations recognize this key
type."
This was true at the time of writing. It's tricky to update
those pages once they've been printed.
If there's a contradiction, always go with the official docs
bundled with your version of postfix, which are correct for
your version of postfix.
