[postgis-users] Evenly distributing a point set

If I had a table of points which are irregularly distributed and wanted to evenly distribute them what would be the best strategy and query?

These points were created from a GPX file along a road journey so they crudely map to a line string.

I was thinking compute the KNN distance for each point and remove those that have a KNN < a threshold (say 100 metres)

Is that the best way to go about it?
