RE: Permissions on Tables

Try using adding -E option to psql. It will show you the queries used to
answer \d* (and other) commands.

psql -E test
test=> \dp
********* QUERY *********
SELECT relname as "Relation",
       relacl as "Access permissions"
FROM   pg_class
WHERE  ( relkind = 'r' OR relkind = 'S') AND
       relname !~ '^pg_'
ORDER BY relname
