You misunderstood me a bit. I mean following test:

fk_count = #box.space._fk_constraints:select()

box.sql.execute('CREATE TABLE t4(x INTEGER PRIMARY KEY REFERENCES t3, a INT UNIQUE, c INT REFERENCES t3);’)

Here creation of last FK fails - for instance due to type mismatch.
Then, number of created FK constraints (and indexes) should be unchanged:

fk_count == #box.space._fk_constraints:select()
index_count == #box.space._fk_constraints:select()

Note that FK constraints are created after indexes.
