Hmph, or more simply:
regression=# select array_in('{1,2,3}',23,-1);
server closed the connection unexpectedly
which is a case that worked before. The core of the problem is
that array_in() violates the assumption that a polymorphic result
requires a polymorphic argument:
regression=# \df array_in
List of functions
Schema | Name | Result data type | Argument data types | Type
------------+----------+------------------+-----------------------+------
pg_catalog | array_in | anyarray | cstring, oid, integer | func
(1 row)
I see that enforce_generic_type_consistency did not use to assert
that it'd resolved every polymorphic rettype. So I think we should just
remove that assertion (and fix the incorrect comment that led to
adding it).
