Saving the information to file can reduce the number of address probes.
As of Postfix 2.6 this information is stored in a btree file by default.

You can retrieve the information from the maillog file.
The database is private to Postfix, meaning that there is no support
for non-Postfix programs that depend on its format. "No support"
means no help writing such programs, and no help updating such
programs when they break after a database format change.
