Subject: [PATCH] fix panic selecting insert_at (#2009)

Fixes a panic at start-up for plugin + postgres/mysql. When selecting on a timestamp database type, the type of the var to scan into is different based on database type. The fix is to convert the timestamp to string within the query and scan into a string.
