I've seen a few requests on how to make FTS search on the absolute value of integers. This question is usually driven by the fact that the text search parser interprets a separating hyphen ("partnumber-987") as a minus sign.
There is currently no good answer for this that doesn't involve C coding. I think this feature has a natural and trivial home in the dict_int extension, so attached is a patch that does that.
There are no changes to the extension creation scripts, so there is no need to bump the version. And I think the convention is that we don't bump the version just to signify a change which implements a new feature when that doesn't change the creation scripts.
Cheers,
Jeff
