I can no figure out the syntax for directly addressing fields (for example 'order by StateProvence" or "order by gTo.geo_name" instead of order by 3)
This should work ("StateProvence" not gTo.geo_name), but You should remember to use " (quotation mark) when You use camel cased names. If not PG will treat fields names like written in small letters.
You should do something like this:
order by "StateProvence"
not
order by StateProvence
I would like to be able to filter and sort the sub-query in the parent query.
I don't get it, I assume You would like to sort/filter sub-query result in parent query. Then You should remember to use names of sub-query result columns i.e
gTo.geo_name is not visilbe, but geolist."StateProvence" is visible outside sub query
