How to make a query to the Postgres data dictionary to find out all the privileges that a particular user has.
I've been looking for a solution and I can not find anything. Thanks and good day
PostgreSQL: Show all the privileges for a concrete user

Table permissions:
SELECT *
FROM information_schema.role_table_grants
WHERE grantee = 'YOUR_USER';
Ownership:
SELECT *
FROM pg_tables
WHERE tableowner = 'YOUR_USER';
Schema permissions:
SELECT r.usename AS grantor,
e.usename AS grantee,
nspname,
privilege_type,
is_grantable
FROM pg_namespace
JOIN LATERAL (SELECT *
FROM aclexplode(nspacl) AS x) a
ON true
JOIN pg_user e
ON a.grantee = e.usesysid
JOIN pg_user r
ON a.grantor = r.usesysid
WHERE e.usename = 'YOUR_USER';
Not sure what this does, but all query results are empty. Yet my user can access their own databases, tables and even peek into foreign databases and create/delete new tables there! This answer doesn't help. –

@ygoe: if a user owns a table (or database), no special grant exists as the owner of an object always has full access to that object (without grants) –

Note:
JOIN LATERAL is available in Postgres from version 9.3 thus the schema permissions query above will not work in AWS Redshift. –
Astrophysics That seems all fine and good for database objects. How does one find the existing privs for a role to the databases themselves? thanks –
Mesocarp
would you mind, to spell out the display of SCHEMA privileges in more detail @Jeff? –
Hymenium
This Schema permissions query does not work well, particularly with AWS, because
pg_user only has users that can log in, so the joins fail when grants are made by roles which cannot log in, which is the usual case for AWS, and because it ignores permissions granted via PUBLIC. I suggest you use my query instead. –
Wegner This is what worked for me the best. short and clean.
\du lists all user accounts and roles and \du+ is the extended version which shows even more information.
# \du
List of roles
Role name | Attributes | Member of
--------------------+------------------------------------------------------------+-----------
padmin | Superuser, Create role, Create DB | {}
test | | {}
postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
root | Superuser, Create role, Create DB | {}
# \du+
List of roles
Role name | Attributes | Member of | Description
--------------------+------------------------------------------------------------+-----------+-------------
padmin | Superuser, Create role, Create DB | {} |
test | | {} |
postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {} |
root | Superuser, Create role, Create DB | {} |
This query shows attributes, the question asks for privileges. –

This command was helpful for me:
\l
Here's how I used it:
postgres=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
------------------------------+-----------------+----------+---------+-------+-------------------------------------
mydb1 | postgres | UTF8 | en_NG | en_NG | =Tc/postgres +
| | | | | postgres=CTc/postgres +
| | | | | myuser=CTc/postgres
mydb2 | postgres | UTF8 | en_NG | en_NG | =Tc/postgres +
| | | | | postgres=CTc/postgres +
| | | | | my_user=CTc/postgres

That's all.
I hope this helps
You can use this script to retrieve all priviliges for all PostgreSQL roles (server level, db ownership, object ownership, object permission, schema permissions). Add filters to get privileges for a specific user

The answer from Vao Tsun regarding how to see permissions for schemas is outdated and potentially hides a lot of results (because pg_user only has users that can log in, so the joins fail when the grantor or grantee is a role that cannot log in). Use this instead:
Show schema permissions (2023)
The following lists schemas and permissions for the current database.
WITH users AS (select rolname, oid
from pg_roles
union
select 'PUBLIC', 0)
SELECT r.rolname AS grantor,
e.rolname AS grantee,
nspname as schema,
privilege_type,
is_grantable
FROM pg_namespace,
aclexplode(nspacl) AS a
JOIN users AS e
ON a.grantee = e.oid
JOIN users AS r
ON a.grantor = r.oid
-- Add a WHERE clause to limit results to a single user
-- WHERE e.rolname = 'PUBLIC' or e.rolname = 'THE_ROLE_YOU_WANT'
Below are queries that return the direct privileges a role/user has been granted - and by that I mean:
GRANTs on/OWNERships of databases, tablespaces, parameters, schemas, tables (including the table-like views, materialized views, partitioned tables and foreign tables), table(-like) columns, sequences, functions, procedures, large objects, types (base, composite, enum, pseudo, range and multirange), domains, languages, foreign-data wrappers, and foreign servers
(Note there is no concept of OWNERnership of parameters, nor of table(-like) columns independent from each column's table)
GRANTs of membership to other roles
The ability to login, create roles, create databases, and if they're a superuser
But not including anything granted to the PUBLIC role
Notes:
- Because only direct privileges are returned, any privileges inherited from role membership are not included.
- Depending on the query, on a database with quite large catalog tables (at least for my world), for me they take between ~10ms and ~20ms.
- The privilege_type column contains PostgreSQL-known privilege types, with the addition of
MEMBER,OWNER,LOGIN,SUPERUSER,CREATE ROLEandCREATE DATABASE - Login, role-creation, database-creation and superuser status is cluster-wide - i.e. independant of the currently connected database
- Role memberships and permissions on databases, tablespaces and parameters are also cluster-wide
- Everything else returned is only for the currently connected database.
- Parameters and table(-like) columns have no concept of ownership.
- For permissions stored with the role, it uses
pg_roles. For role membership, it uses pg_auth_members. And for everything else, it goes via pg_shdepend to determine OWNERship, and lead to the pg_* catalog table in question that stores ACL-permissions. While this makes the query long, I think by going via pg_shdepend it can be more efficient when there are many rows in the catalog tables - avoiding full table scans of pg_class for example when it's very big.
Example output:
on | name | privilege_type
----------------------+-----------------------------------------+----------------
cluster | | LOGIN
role | other_role | MEMBER
database | new_database | OWNER
database | postgres | CONNECT
schema | my_schema | USAGE
table | my_schema.my_table | SELECT
sequence | my_schema.my_sequence | USAGE
table column | my_schema.my_table.id | SELECT
table column | my_view.id | SELECT
function | prod(double precision,double precision) | OWNER
aggregate function | incremented_max(integer) | EXECUTE
large object | 175076 | SELECT
composite type | my_schema.compfoo | OWNER
domain | my_schema.mydom | OWNER
composite type | my_schema.compfoo | USAGE
pseudo type | "any" | USAGE
language | sql | OWNER
language | sql | USAGE
tablespace | my_new_tablespace | OWNER
foreign-data wrapper | dummy | USAGE
foreign server | myserver | OWNER
parameter | max_connections | SET
And the query is:
-- Cluster permissions not "on" anything else
SELECT
'cluster' AS on,
NULL AS name,
unnest(
CASE WHEN rolcanlogin THEN ARRAY['LOGIN'] ELSE ARRAY[]::text[] END
|| CASE WHEN rolsuper THEN ARRAY['SUPERUSER'] ELSE ARRAY[]::text[] END

Or if you want slightly more structured output that can more easily be used (once safely quoted/escaped) in further SQL to manage permisisons:

Answer from 2k24: there is \dp concrete_TABLE - but it works "other way around" - get's you privileges by table (view, sequence), not by user:
\dp [PATTERN] list table, view, and sequence access privileges
Usage:
=> \dp some_things
Access privileges
Schema | Name | Type | Access privileges | Column privileges | Policies
--------+-------------+-------+---------------------------+-------------------+----------
public | some_things | table | dba=arwdDxt/main-db +| |
| | | metabase=r/main-db +| |
| | | jane_dou=arwdDxt/main-db | |
(1 row)
You can also just use this to see if your user has anything other than SELECT
SELECT * FROM information_schema.role_table_grants WHERE grantee = 'username' AND with_hierarchy = 'YES'
