I'm not sure about fedora, but on NetBSD 3.0rc5 , postgresql 8.1.3 I
can see the
same behaviour:
am=# select version(); version
--------------------------------------------------------------------------------------------PostgreSQL 8.1.3 on
i386--netbsdelf,compiled by GCC gcc (GCC) 3.3.3
(NetBSD nb3 20040520)
(1 row)
am=# SELECT '-10e400'::float8;
ERROR: "-10e400" is out of range for type double precision

Sure .

Yes, I'm getting the same output (both on cygwin and netbsd 3.0rc5):
$ ./test-strtod.exe
double: -inf, errno: 34, tail: '', isinf: 1, fabs: inf,inf>max: 1
