Huh.  Works for me ...

Either your logging is broken or you're looking in the wrong log, I
think, because that sure looks like a backend crash.  And the postmaster
would certainly bleat about a backend crash.

Dunno, have you messed around with either casting or round()?  Can you
reproduce this in a freshly-created database?

FWIW, a stock database ought to have these versions of round():

postgres=# \df round
                          List of functions
   Schema   | Name  | Result data type | Argument data types |  Type
------------+-------+------------------+---------------------+--------
 pg_catalog | round | double precision | double precision    | normal
 pg_catalog | round | numeric          | numeric             | normal
 pg_catalog | round | numeric          | numeric, integer    | normal
(3 rows)
