Обсуждение: Feature-Request: Login-Procedure
Hello, Someone asks for a Login-Procedure like Sybase: set OPTION PUBLIC.LOGIN_PROCEDURE='meine_tolle_prozedur'; I think, this i possibly a nice feature, either per user or for all users. We have a 'ALTER USER name SET parameter ...', simply add a new Parameter 'login_procedure' and call this procedure? Any comments?

I'm amazed ;-) There are other clients?

I'm amazed ;-) There are other clients? I have the impression most people are working via some kind of other application which is using postgres as invisible backend :-) Btw, greating can be done via .psqlrc or so too :-) Regards Tino

Or maybe even use it to update their password expiration date to NOW()+30 DAYS, so that the data base automatically expires accounts that aren't being used. Regards, Berend Tober

While there are certainly things neither you nor I have thought of that a login fired procedure could be useful for, there are also going to be cases of people "reinventing the wheel" with it, i.e. doing things that should probably be in pg_hba.conf. OTOH, only the postgres account holder can edit the pg_hba.conf and reload the database, while you could easily have a user editable table referred to by a login proc that did something similar, and have the permissions set so that a certain class of users (i.e. help desk folks) could edit the settings for a user. I think a login proc is more of a plus than a minus... But I'm not the guy slinging the code (I've been working 60 hours a week for the last three months... I barely have time to monitor the lists and answer simple questions...)
