David Rowley e6b0efc65e Ensure we allocate NAMEDATALEN bytes for names in Index Only Scans 
As an optimization, we store "name" columns as cstrings in btree
indexes.

Here we modify it so that Index Only Scans convert these cstrings back
to names with NAMEDATALEN bytes rather than storing the cstring in the
tuple slot, as was happening previously.
