Re: List Permissions

Thanks for the replies.
  Actually this was question posed by one of my colleagues, what he really wants to know is if there is the equivalent of MySQL's

select * from all_tab_privs_recd where grantee = 'your user'

Thanks again,
Brett

  How can I list a users permissions table by table?

  i.e.  User Joe
 has read/write on table1

 has read on table2
 no access on table 3

For a particular user you can use below function. You can write a SQL query or script which takes table names from "pg_tables" one by one.

has_table_privilege(user, table, privilege)

Example :

I am checking if user "postgres" has "select" privilege on "table1".

postgres=# select has_table_privilege('postgres','public.table1','select');

has_table_privilege

---------------------

 t

(1 row)

For current user (user you logged in as) you can use the following function

has_table_privilege(table, privilege)

I am checking if the current_user has "select" privilege on "table1"

Example:

postgres=# select current_user;

current_user

--------------

postgres

(1 row)

postgres=# select has_table_privilege('public.table1','select');

has_table_privilege

---------------------

 t
