Thread: PGError: input out of range
My database just had this new error, and I have no idea why (because I
haven't intentionally made any changes to this table). Does anyone have an
idea which input is out of range-- or what the problem might be?
Thanks,
Dustin

The only thing in your query that I can imagine being out of range is ACOS() which would need to be between -1 and 1 (otherwise the result would be complex). I'd try and see what the argument to the ACOS is, but it's probably some corner case where the rounding is getting you.

I see no such error string in the current sources ... what Postgres
version are you using?
If you set "\set VERBOSITY verbose" in psql before trying the query,
you should get some extra info about where the message is coming from.

The problem was indeed ACOS() being outside of the [-1,1] range, and this happened because it was calculating the distance between the same LAT,LONG pair (the same location) I added a WHERE L1.ID <> L2.ID to stop the reflexive calculation.
