You can achieve this goal by revoking certain privileges. You might have the reasons to do so - the only scenario where I'd start thinking about it is multi-tenancy. Still, in this case, it is bette …

What you see typically happens when the non-privileged user doesn't have schema level privileges. In this case, they cannot list the objects inside the given schema - with the command you tried. See …

I think you cannot do this using only the tools PostgreSQL offers. On one hand, there are no default privileges, as you noticed. The REVOKE command issued on a template DB (template1 in most cases) …

You will have to edit your pg_hba.conf file. If you really want to reduce possible access to a single user (see the note below), you will need the following lines, and only these: # TYPE DATABASE …

Looking up the documentation, two things to mention: not sure whether a space is allowed before @ (not declared explicitly, but the user string takes the user_name@host_name form - and since this is …

If you need to do this only once, the quickest way is probably the following. Find all the schemas you want to touch by querying, for example, the pg_namespace system catalog: SELECT nspname FROM p …

The problem here is the ALTER DEFAULT PRIVILEGES statement you issued will apply only to tables that are created by user_name: You can change default privileges only for objects that will be created …

As it sounds, the tables (not necessary the database) is owned by the app user. This is what the documentation tells about this: If the "Access privileges" column is empty for a given object, it …

Postgres is quite good at doing such things, this is one reason I like it. You can create an arbitrarily complex role hierarchy, but for our purposes a simple one will be enough: CREATE ROLE student …

According to the documentation, what one needs for creating tables in a schema is CREATE on that schema. This you think you revoked, but as you experience it didn't really happen - the only plausible …

I try to answer your question - to be correct, I try to answer the question I think you've asked (see the comments). Until then I'll assume that a virtual table is simply a table and you want to coun …

The documentation of GRANT says the following: CREATE For databases, allows new schemas to be created within the database. For schemas, allows new objects to be created within the schema. To ren …

The CONNECT privilege for PUBLIC looks somewhat special: \l template1 | postgres | UTF8 | Hungarian, Hungary | Hungarian, Hungary | postgres=CTc/postgres That is, user test (which is the memb …

arwdDxt/bob ↵│ │ │ │ alice=r/bob │ As you can see, despite creating the table in alice's schema where she set the default privileges, bob's table doesn't have all those permissions …

There is no builtin role like that in PostgreSQL. However, you can set up one: CREATE ROLE db_datawriter; After this, you have to assign write privileges (usually INSERT, UPDATE, DELETE, maybe TRU …
