Alvaro Herrera ad86d159b6 Add 'missing_ok' argument to build_attrmap_by_name ...

When it's given as true, return a 0 in the position of the missing
column rather than raising an error.

This is currently unused, but it allows us to reimplement column
permission checking in a subsequent commit.  It seems worth breaking
into a separate commit because it affects unrelated code.
