Hi,

I'm looking for a function in postgresql which notify the client if a table was full or not.So I found the function Notify https://www.postgresql.org/docs/9.0/static/sql-notify.html.

This function send a notification when a new action was done to the table. Is there a way to send a notification only  when the table was full and no future actions (insertion of new rows for examples) will be done. I was connected to an external api and saving the data received from it to a postgres database and I want to be notified when the table was full and no rows will be inserted. Does it realizable or Should I create a trigger and listens for every insertion and notify the client?

​The only way a table becomes "full" is if you run out of disk space - and you should be monitoring that at the O/S level and not at a database table level...

​As for clients - if they are inserting data they will simply get failures when they attempt to do so - for me that seems like sufficient notification for something that should rarely if ever happen.
