Looks good. Go ahead and commit this. 


Thank you, I appreciate the contribution. 


I'll take a look at making the completion REQUIRE-MATCH change separately; I do 
think that control of completion behavior is needed here but it impacts more 
than just database selection for Postgres. The advantage of adding a keyword to 
the `sql-product-alist' is that the user can control the behavior to meet their 
preferences.
