Sure. And they will accept mail for everything in the database, you will have 
no good routing as any given setting applies to any given postfix 
installation, unless you maintain internal DNS and transport maps locally and 
very carefully.
So my own database has a 'servers' table and transport / relay are 
applied per server. This way an incoming mailhub accepting for all domains can 
get transport info from the same database and multiple transport maps can be 
applied for the same domain, pending the role of the server in the mail 
network that requests the info. Postfix (and dovecot) maps simply have a WHERE 
me='mailhub.example.com' clause.
