More exactly they are sent separately:
null indication is per row 'D'/'B' and type specification is per query 'T'.

If the client does not ask for metadata one might omit attrelid,attnum 
(*) and field name in the 'T' packet. One might argue whether this small 
win per query times column rectifies to implement the feature. But then 
we'd need a method to query them lateron (otherwise *DBC could never 
omit them at first).
