table2csv consumes too much memory

[papousek]

table2csv (proso_common) dumps tables from database to csv to make them available for offline analysis. The command uses this function (https://github.com/adaptive-learning/proso-apps/blob/master/proso/db.py#L11) which should already handle the memory consumption. Unfortunately, it seems it doesn't work. See the attachment from www.slepemapy.cz (table2csv is executed by cron at 3:00)
