Обсуждение: Questions on setup and usage
We have a commerical application which we currently are running under a different database but would like to consider a enterprise version using PostGres. There are several features in this other database that have become important to us.
1. The ability to encrypt stored procedures and triggers. I know that PostGres doesn't have this feature but is there a way to protect stored procedure and trigger source yet allow it to be executed by any user and how would it be done.
2. We do not want the table schema to be accessed by outside applications. Since our application is so normalized, accessing these tables directly will not make a lot of sense to our users so we create views that are more user friendly for doing reports, accessing the data via Excel, etc. How would we do this in Postgres.
3. We use active directory to validate a user's login. We have "rules" and functionality security built in as stored procedures. How would we do this under Postgres. We do this with a configuration variable during the login process stored process. If the company uses active directory we use it to validate the user, if not then we present a user login and require that a login be manually entered. For those companies that use active directory we try to have our application validate the AD so that the user isn't required to multiple applications.

You could put the tables in a separate schema, which you would not put on the default search path. The views could refer to the tables with the schema qualifier. This would not hide the tables from the users, per se, but would cause them not to show on casual display, or allow them to be accessed without explicitly specifying the schema. > 3.

Please keep the list copied. Also, it's best to quote the minimum required for context, and to avoid top-posting. (It's much easier for most people to read this way.)

I believe so, but I'll leave the details to those more familiar with the issue. -Kevin
I know that by using lowercase object names that I can work with those object in a case insensitive way, however is there a way through maybe a locale or character set to make the data and the indexes case insensitive such that you don't need to use ILIKE?
