All-
I've traditionally used stored procedures in other databases as a means to control access to tables for create, update, and delete (CUD) operations, prohibiting arbitrary access and ensuring data integrity, etc. Ordinary users are prohibited from accessing tables directly and, instead, must use the procedures provided to perform modifications (while still being able to perform arbitrary queries on the data).
I just started working with privileges on Postgres and I can't seem to implement a similar scheme. For example, if a stored procedure inserts a row into a table, the user must have insert privileges on the underlying table which would allow arbitrary, and potentially prohibited, modifications.
Is there a way to implement this pattern on Postgres?
