I've found some odd behaviour in ST_SnapToGrid, which looks like a bug.
When I run
SELECT ST_SnapToGrid(ST_Transform(ST_GeomFromText('POINT(180 50)',
4269), 4326), 0.00001)::geography
an error is returned:
ERROR: Coordinate values are out of range [-180 -90, 180 90] for
GEOGRAPHY type
Calling ST_AsText() on the same geometry returns "POINT(180 50)", as
expected. Interestingly, if I either decrease or even increase the
precision the error does not occur. Eg. this works fine:
SELECT ST_SnapToGrid(ST_Transform(ST_GeomFromText('POINT(180 50)',
4269), 4326), 0.000001)::geography
It's only the value 0.0001 that seems to cause a problem. Is this a bug
or am I missing something?
Regards,
Evan
