[postgis-users] extra function?

[Stephen Crawford]

Should I have both _st_summarystats and st_summarystats in my database?  
I get messages like "function not unique" and "could not choose best 
candidate function" when doing this:

SELECT rid, observation_date, ST_SummaryStats(rast::raster, 
true::boolean) FROM spring_ms WHERE observation_date = '2012-02-20';

I expected to get 187 records (one for each tile).

Thanks,
Steve
