[postgis-users] Distance() vs ? - performance

[Tyler Mitchell]

Dave answered my question earlier, but now I'm wondering if there is a 
trade-off on memory/temp space usage.

I'm trying to compute a distance between two tables of features and find 
my temporary files fill up the drive and kill my query. 
My query involves computing the distance from polygon features to the 
nearest line feature (i.e. polygons -> road line).  So I can't use && to 
optimize the query because they are very discontiguous.

Any recommendations?
