Обсуждение: Problem with GIST-index and timestamps

Hello,

i wanted to define and GIST-index on a table with a timestamp-column
containing 'infinity' values, and it throws the following error:

ERROR:  cannot subtract infinite timestamps

Is this a known limitation?
How can i avoid or circumvent this?

Thanks in advance

Sebastian

Ok, so let me ask wether it's a bug or not.

Sure they do, but they're not quite useful in my situation.

Thanks
