Hello,
My reason/excuse for asking what I'll eventually ask is that I'm a new PostgreSQL practitioner so the amount of things I don't know about PostgreSQL is depressingly large.
While reading through the recent "Row level security - notes and questions" thread I saw this SQL statement:
CREATE POLICY accounts_policy ON testrls.accounts
FOR ALL
TO users
USING (true)
WITH CHECK (username = SESSION_USER);
While reading through the recent "Row level security - notes and questions" thread I saw this SQL statement:
CREATE POLICY accounts_policy ON testrls.accounts
FOR ALL
TO users
USING (true)
WITH CHECK (username = SESSION_USER);
The bit that is the catalyst for this e-mail is: SESSION_USER.
As a recent convert to the Church of Postgres I've been consuming vast amounts of information on PostgreSQL, and SESSION_USER is not the first nor only, what I'm calling magic constant, that I've seen. Off the top of my head, other examples that I've encountered are CURRENT_USER and CURRENT_TIMESTAMP.
So my question is this, is there a reference table in the documentation that I haven't found yet that lists all magic constants and their meaning? And if not in the official documentation is it in the wiki?
Thanks,
Dane
