[OSM-newbies] Howto: Query to get max speed limit of nearby road/highway

[René Fournier]

So... I've imported 27 GB of canada.osm into PostGIS 1.5.4. Now I am trying to construct a query that, given a point (latitude, longitude), finds the max speed limit of the road it is on (or within 10 meters of — otherwise, return nothing). Can anyone help? I'm a total OSM noob, and have no idea how the data is structured or how best to extract this one piece of information. Thanks!
