Seems you accidentically replied to me only.

Postfix uses the filename you provide as name for the db file, so 
running it against symlinks does follow the symlink, but it uses the 
symlink name as what it uses to create the .db file.

You can test this by creating file and doing symlink for it and running 
postmap against the symlink. You'll see that it will create 
symlink-name.db file instead of file.db.
