Hello, everybody!
As Nikita requested, I performed the patch to remove
box_index_by_name() from build.c and pragma.c, but what about
analyze.c? Still had to add space_index_by_name() to use in
pragma.c, beacuse struct index is required.

Roman Khabibov (3):
  sql: improve "no such constraint" error message
  sql: don't select from _index during parsing
  sql: support constraint drop
