A few points:

1: GEOS-driven ST_IsValid raises a NOTICE containing the reason, home-made
   version should do the same.
2: I see you're not handling nan, just infinite. Is that intentional ?
3: GEOS-3.2 also survive the inf/nans in GEOSValid, why checkin for 3.3+ ?
4: Expecting the error in tickets.sql makes the whole test file
   pass or fail based on the version of GEOS you built postgis against.
