There are same bug in int8 and timestamp[tz] versions.
We also need fix for them.
=# SELECT x FROM generate_series(9223372036854775807::int8,
9223372036854775807::int8) AS a(x);
=# SELECT x FROM generate_series('infinity'::timestamp, 'infinity', '1
sec') AS a(x);
=# SELECT x FROM generate_series('infinity'::timestamptz, 'infinity',
'1 sec') AS a(x);

They work as expected in 9.1dev.
