On Thu, 26 Mar 2009, I wrote:
release-16.0-preview-14-mar=# \d location
Table "public.location"
Column | Type | Modifiers
-----------------+---------+-----------
end | integer |
start | integer |
objectid | integer |
id | integer | not null
Indexes:
"location__object" btree (objectid, id)
"location__start" btree (start)
"location_bioseg" gist (bioseg_create(intermine_start, intermine_end))
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.
