Implement login cookie, its verification, and logout At first i thought that i would need to implement sessions, the ones that keep small files onto the disk, to know which user is talking to the server, but then i realized that, for now at least, i only need a very large number, plus the email address, to be used as a lookup, and that can be stored in the user table, in a separate schema. Had to change login to avoid raising exceptions when login failed because i now keep a record of login attemps, and functions are always run in a single transaction, thus the exception would prevent me to insert into login_attempt. Even if i use a separate procedure, i could not keep the records. I did not want to add a parameter to the logout function because i was afraid that it could be called from separate users. I do not know whether it is possible with the current approach, since the settings variable is also set by the same applications; time will tell. 2023-01-17 19:48:50 +00:00			`-- Verify numerus:logout on pg`
