* create a view with new and old timestamps and user ids with
`create or replace view "user_new" as select "user".id, "user".timestamp, date 'epoch' + "user".timestamp * interval '1 second' as timestamp_new from "user";
* create temporary timestamp column in user table with
`alter table "user" create column "timestamp_temp";`
`alter table "user" add column "timestamp_temp" date;`
* fill temporary timestamp column with new timestamps with
`update "user" set timestamp_temp = (select timestamp_new from from user_new where user_new.id = "user".id)`
`update "user" set timestamp_temp = (select timestamp_new from user_new where user_new.id = "user".id);`
* check if new timestamps look sane
* drop old timestamp column
`alter table "user" drop column timestamp cascade;`
