Trying to figure out how to reference a field in a cursor result, or in a row/record variable that I've FETCHed the cursor into, where the target field name is in a variable or parameter. I think I'm just missing the dereferencing syntax. I've studied the manual and tried using EXECUTE to no avail.
Worst case, if I could just reference the Nth field, then I could combine with pg_attribute info to get what I need.
