So, it would be useful if we could make the location_bioseg index a
multi-column index, like this:
CREATE INDEX location_bioseg3 ON location USING GIST (objectid, bioseg_create(intermine_start, intermine_end));
However, I get the following error message:
ERROR: data type integer has no default operator class for access method "gist"
HINT: You must specify an operator class for the index or define a default operator class for the data type.
Is there an operator class for integer for gist indexes that I can use?

And why do I do it that way? Because I wish to remain sane. Um, actually,
maybe I should just say I don't want to be any worse than I already am.
