Re: unnest multirange, returned order - Mailing list pgsql-docs

Trying a suggestion then:

"""

unnest ( anymultirange ) → setof anyrange

Expands a multirange into a set of ranges. The ranges are read out in storage order (ascending) and therefore cannot be relied upon.

unnest('{[1,2), [3,4)}'::int4multirange) →

 [1,2) [3,4)

"""

I personally think that it is clear as it is written now.

If you have a good suggestion for an improvement, you could send it;
perhaps someone will pick it up.
