G'day. I just hit the same issue, and resolved it instead by using the proxymap service to allow access from verify in the chroot up to the database in /var/lib/postfix.
The required changes were: address_verify_map = proxy:btree:$data_directory/verify_cache proxy_write_maps = $smtp_sasl_auth_cache_name $lmtp_sasl_auth_cache_name $address_verify_map 'proxy_write_maps' had the first two entries by default, and I manually added the third to permit read/write access to that proxy map.
