estimate_extent with PostGis 2.1.0

[divya1c]

Hi!

I set estimated_extent parameter to true in my xml file, and I get these warnings -
CONTEXT: SQL function "st_estimated_extent" during startup
WARNING: ST_Estimated_Extent signature was deprecated in 2.1.0. Please use ST_EstimatedExtent

Is there a way to avoid these warnings? I am using PostGis 2.1.0.

Thanks!

Thanks for catching this, looks like they renamed the function :(.

Overall using estimated_extent is not a great idea. It is better to just get the extent via ST_Extent manually from postgis for your table and then use that to populate the extent parameter for Mapnik.

In my case, extents will be different for different users in the system. Would you recommend any good way of doing this?

Thanks :)

@divya1c yes: dynamically create your mapnik styles per user, then cache them.

Great! thanks! will try that.
