Check with db_dump what the difference of these databases is. db_dump is a
tool from the Berkeley-Utilities. Maybe already installed on your system.

# db_dump -p sasldb2

# db_dump -p virtual.db

Here it shows with some sample-Data:

# db_dump -p /etc/postfix/sasldbtest.db
VERSION=3
format=print
type=hash
h_nelem=4097
db_pagesize=4096
HEADER=END
 user\00
 password\00
DATA=END

# db_dump -p /etc/sasldb2
VERSION=3
format=print
type=hash
db_pagesize=4096
HEADER=END
 user\00domain.tld\00userPassword
 secret
DATA=END
