Error********** ERROR: invalid return type SQL state: 42804 Detail: SQL key field type text does not match return key
fieldtype integer.
Try:
select * from connectby('emp','empid','mgrid','1','0')
AS t(keyid integer, parent_keyid integer, level int);
connectby() was made more strict about the datatypes matching in 9.5.
See commit 37507962c3d2123b0f21c50d6172fd0b1e059fe7.
