Does PostgreSQL implement Geospatial relationship queries?

Question

My company is looking at different database providers, and how they implement Geospatial queries to get distances from a Lat/Long for a number of records.

We are going to investigate PostgreSQL as a potential database platform.

• I've heard that PostGRE implements Geospatial queries. Is this correct?
• Is there a good reference somewhere that gives info on the implementation?

Answer 1

It's PostGIS. For reference you have manual, wiki and more...

Answer 2

If you want to spatially enable a PostgreSQL database you can do so with PostGIS, it's compliant with the Open Geospatial Consortium's Simple Features Interface Standard for SQL too.
