My guess (you neither provide postconf -n output, nor specify what
postmap incantation was used to create the virtual.db file) is that
the .db files in question may not of the expected dictionary type.
Perhaps they're "hash" instead of "btree", or "btree" instead of "hash".
Another possibility is that the postmap(1) binary in question is linked
with a different Berkeley DB library than smtpd(8) (mixed Postfix install
with admin utilities in sbin from a different Postfix version than the
libexec daemons).
