Hello everyone, I'm working with an application, and I'm realizing that perhaps the model for security that I have used in the past won't work all that well with the application that I'm working on. I am certain that this particular model is how web applications traditionally work, but I am wondering if I can do something a little more then this in PostgreSQL. Traditionally, I have a table that contains the user names and hashed passwords for each of the users that are defined to the application. When they login, it checks against this table, and so forth. However, the application that I'm currently working on is something that I want to have a portable set of front-ends to work with. For example, I'd like a front-end in PHP for web-based access, but also I am working on creating a front-end that will be written in a more client/server fashion. I'd like to know if I can constrict database and data access on a row-level with PgSQL by using some sort of trickery in the database configuration itself. If not, that's okay, I suppose -- it'll just mean that I'll need to come up with my own client/server portions of the program, with the server side of it regulating the access. That will make it significantly more of a challenge, but it is the only other thing that I can come up with. Ideas? Thanks, Mike
