Linq's syntax symmetry with Postgres

Can't help but notice, Linq multiple condition has more affinity with Postgres flexible syntax:

from c in Customers
join o in Orders on new {c.CompanyID, c.CustomerID} equals new {o.CompanyID, o.CustomerID}

Postgresql:

from Customers as c 
join Orders as o on (c.CompanyID,c.CustomerID) = (o.CompanyID,o.CustomerID)
