My main issue with database connections for configration and  
sessionfactory building
is:

1) The database might not be needed at all (e.g. for pure codegeneration  
 from the metadata)

2) The database might not be running at all when doing development  
(related to 1)

3) It can be *really* slow to create connections and read metadata (gives  
bad user experience in an ui)

4) Not all users have access rights to read this metadata information

So iff this gets added to the dialect then I would say the following  
should be true:

1) There should be an option/flag for not giving the dialects the option  
to spend time getting the metadata

2) Since the dialects might not get the connection or the user does not  
have proper rights to inspect the metadata they should
have sensible defaults anyway  - or even be able to get the base  
information like major/minor version from other settings etc.
