There is no CREATE OR REPLACE AGGREGATE which means that the only way to replace an aggregate is to DROP then CREATE which is problematic as it will fail if the previous version of the aggregate has dependencies. This commit makes sure aggregates are not dropped and recreated every time. NOTE that WHEN CREATING NEW FUNCTIONS in sql/aggregates.sql you should also make sure they are created in an update script so that both new users and people updating from a previous version get the new function. sql/aggregates.sql is run only once when TimescaleDB is installed and is not rerun during updates that is why everything created there should also be in an update file. Fixes #612
