All,
I'm trying to implement row level security using PostgreSQL. I envision
having column on each and every table in the database that will contain a
discriminating value that determines if a given user is able to see that row
or not. Users do not directly access the database; they get at it only
through client applications.
Is there a way to initially configure PostgreSQL such that each and every
time a 'create table foo....' command is executed that, something else would
happen instead?
For example,
CREATE TABLE weather ( city varchar(80), lo int, hi int, prcp real, date date
);
would result in the following being executed automatically:
CREATE TABLE t_weather ( city varchar(80), lo int, hi int, prcp real, date date,
hidden_column int
);
CREATE VIEW weather AS SELECT city, lo, hi, prcp, date FROM t_weather;
How the view gets populated is another discussion entirely.
But is there a way to set things up initially such that each 'create table'
command will exhibit the behavior described above?
Thanks.
