The tmp_XXX tables has no permissions assigned to it and I want to assign it with the same owner and access privileges of XXX table. I had a look on pg catalog tables http://www.postgresql.org/docs/8.4/static/catalogs.html to create a stored procedure to do this job for me. I have found some tables which might be useful to get the original table iformation. For example, I can use pg_table to get the owner of the original table. Also, I have found pg_roles. However, I was not able to find where the access privileges are stored.
Is there a better way to do this task than extracting the access privileges from pg catalog ? If not, where I can find the access privileges information ?
