It seems to be not a problem with the number but the exponentiation and
casting:
test=# create table bigint_test (int_fld int8);
CREATE TABLE
test=# insert into bigint_test values (9223372036854775807);
INSERT 0 1
test=# select * from bigint_test ; int_fld
--------------------- 9223372036854775807
test=# select 2^63-1; ?column?
---------------------- 9.22337203685478e+18
(1 row)
test=# select (2^63-1)::int8;
ERROR: bigint out of range
