Disallow infinite endpoints in generate_series() for timestamps.

Such cases will lead to infinite loops, so they're of no practical
value.  The numeric variant of generate_series() already threw error
for this, so borrow its message wording.

Per report from Richard Wesley.  Back-patch to all supported branches.
