Обсуждение: Triggers: How to make one that fires at a certain time of day?

I'd like to have a table that generates a row entry everyday at
midnight. Is there anyway to create a trigger (or something else) that
would fire at midnight and insert a row into a table?

Thanks!

cron? psql "query"...

No; the database knows nothing about the passing of time.

The normal way to do this is to use cron to invoke a script that will
insert the row.
