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).
