Обсуждение: Checking Permissions with SQL

How would I be able to check whether I have select,update,insert,etc
permissions on a given table with an sql statement?

I am working on a generic php interface that lists all or some tables and
lets you edit them.

I want to get away from the permisssion denied error that php gives me.

select relacl from pg_class where relname = 'my_table';

You have to GRANT whatever permissions are needed to the user the web
server run as. vis:-

grant select on school to nobody;
grant select on school_number_seq to nobody;

This enable the web server, which runs as 'nobody' to select and read from
the database.

school=# select relacl from pg_class where relname = 'school';
            relacl

 {"=","chris=arwR","nobody=r"}
(1 row)
