pg_dumpall --exclude-database option

PFA a patch to provide an --exclude-database option for pg_dumpall. The 
causes pg_dumpall to skip any database whose name matches the argument 
pattern. The option can be used multiple times.


Among other use cases, this is useful where a database name is visible 
but the database is not dumpable by the user. Examples of this occur in 
some managed Postgres services.


I will add this to the September CF.


cheers
