I have a table with columns datetime timestamp, value float(8) I want to delete rows 10 days older or 10 hours older by delete from tablename where datetime < TODAY-10; or delete from tablename where datetime between CURRENT-10 and CURRENT; So are there key words TODAY, CURRENT in PostgreSQL? Thank you!
