However, var_samp() and stddev_samp() were merely renamings of the pre-existing aggregates variance() and stddev(), so we could extend support to earlier versions of Postgresql by using those older function names where appropriate.",,closed,"Database layer (models, ORM)",dev,,wontfix,,richard.davies@…,Unreviewed,0,0,0,0,0,0
