We need the number of geometries to pass them to the get score function
in order to get an accurate score for the input in order to suggest
what is the geometry that fits better for the input we have
New function to check the metadata in order to search for errors like
for example if we have the metadata for a median aggregation and the
normalization is by are it'll fail.
Now use the new meta ttable obs_meta_geom_numer_timspan to filter
the geometries by geometries timepsan and/or numerator timespan (which
is what we get when we use the obs_getavailabletimepspans)
The current OBS_GetAvailableNumerators is not designed with our
UI in mind so it's causing a lot of troubles and we're doing so
many hacks to fit our UI needs and the interface of the function so this
function it's a better fit for our purposes.
This function is private because, by now, we don't want to expose
as a public function because could suffer changes in the near future.
Right now we're doing INNER JOINS when we JOIN the _procgeoms and
the data so we end up with NULL value instead of id, NULL value. We need
to have the id available to make the JOIN at the end of the query and
provide results like this:
id | data
----+------------------------------------------------------------------
1 | [{"value" : 858469},{"value" : 73.9397964478},{"value" : 69092}]
2 | [{"value" : 738774},{"value" : null},{"value" : 2235406}]
Fixes#260
* Adds `geom_type`, `geom_extra`, and `geom_tags` to `OBS_GetAvailableGeometries`. This brings it up to spec with existing docs.
* Adds `timespan_type`, `timespan_extra`, and `timespan_tags` to `OBS_GetAvailableTimespans` for consistency.
