use SP-GIST index for building index where available

Browse Source 
Point-in-polygon queries are much faster with a SP-GIST geometry
index, so use that for the index used to check if a housenumber
is inside a building.

Only available with Postgis 3. There is an automatic fallback to
GIST for Postgis 2.
