Andrew Dunstan f30d0c720f Fix COPY TO FORMAT JSON to exclude generated columns. 
COPY TO with FORMAT json was including generated columns in the
output, unlike TEXT and CSV formats.  Virtual generated columns
appeared as null, and stored ones showed their computed values.

The JSON code path only built a restricted TupleDesc when an explicit
column list was given (attnamelist != NIL), but CopyGetAttnums()
also excludes generated columns from the default list.  Fix by
checking whether the attnumlist is shorter than the full TupleDesc
instead.

Bug introduced in 7dadd38cda.
