I admit that in the past I have had some real frustrations granting permission users in PostgreSQL databases. I believe that much of this stemmed from the fact that up until Version 9, there was no way to manipulate the permissions on more than one object at a time, you simply had to grant permissions to each object. Then when another was added more permissions had to follow, it was never ending. Now with version 9, things have gotten simpler. When I have a task such as creating a user with specific access to a schema, I would follow these tasks:.
We will grant select on all of the tables in the schema without having to list them individually:. You may be needing to grant superuser MySQL rights to one of your users.

These variants are similar in many ways, but they are different enough to be described separately. This variant of the GRANT command gives specific privileges on a database object to one or more roles. These privileges are added to those already granted, if any. There is also an option to grant privileges on all objects of the same type within one or more schemas. The key word PUBLIC indicates that the privileges are to be granted to all roles, including those that might be created later.
Any particular role will have the sum of privileges granted directly to it, privileges granted to any role it is presently a member of, and privileges granted to PUBLIC. Without a grant option, the recipient cannot do that. There is no need to grant privileges to the owner of an object usually the user that created itas the owner has all privileges by default. The owner could, however, choose to revoke some of his own privileges for safety.
The right to drop an object, or to alter its definition in any way, is not treated as a grantable privilege; it is inherent in the owner, and cannot be granted or revoked.
However, a similar effect can be obtained by granting or revoking membership in the role that owns the object; see below. The owner implicitly has all grant options for the object, too. The object owner can of course revoke these privileges. For maximum security, issue the REVOKE in the same transaction that creates the object; then there is no window in which another user can use the object.
For sequences, this privilege also allows the use of the currval function. For large objects, this privilege allows the object to be read.
If specific columns are listed, only those columns may be assigned to in the INSERT command other columns will therefore receive default values.
For sequences, this privilege allows the use of the nextval and setval functions. For large objects, this privilege allows writing or truncating the object. To create a foreign key constraint, it is necessary to have this privilege on both the referencing and referenced columns.
The privilege may be granted for all columns of a table, or just specific columns. Allows the creation of a trigger on the specified table. For schemas, allows new objects to be created within the schema.
To rename an existing object, you must own the object and have this privilege for the containing schema. For tablespaces, allows tables, indexes, and temporary files to be created within the tablespace, and allows databases to be created that have the tablespace as their default tablespace. Note that revoking this privilege will not alter the placement of existing objects. Allows the user to connect to the specified database.
Allows the use of the specified function and the use of any operators that are implemented on top of the function. This is the only type of privilege that is applicable to functions. This syntax works for aggregate functions, as well.
For procedural languages, allows the use of the specified language for the creation of functions in that language. This is the only type of privilege that is applicable to procedural languages. For schemas, allows access to objects contained in the specified schema assuming that the objects' own privilege requirements are also met. Essentially this allows the grantee to "look up" objects within the schema.
Without this permission, it is still possible to see the object names, e. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.
This allows you to specify who may do stuff in the database if they have sufficient other permissions. This frequently happens when you create a table as user postgres and then try to access it as an ordinary user. In this case it is best to log in as the postgres user and change the ownership of the table with the command:. Make sure you log into psql as the owner of the tables.
As you are looking for select permissions, I would suggest you to grant only select rather than all privileges. You can do this by:. I was faced with this problem once. Learn more.

Does this affect all databases on the server that use the public schema? If I create a new table, will this user have access to the newly created table? GuiSim No, You have to set the default privileges on a schema, where ytou create the table: postgresql.

Grant Permissions to All Schema Objects to a User in PostgreSQL
This confused me. Still not sure I'm handling it correctly. Here is how I managed to get my other users and groups to work as I needed:. I kept getting this error when using flyway to deploy database changes. I do some manual setup first, such as creating the database, so flyway wouldn't need those super-admin permissions.
I had to ensure that the database user that flyway job used had ownership rights to the public schema, so that the flyway user could then assign the right to use the schema to other roles. RDS reserves super users for use by AWS, only, so that consumers are unable to break the replication stuff that is built in. However, there's a catch that you must be an owner in postgres to be able to modify it. My solution was to create a role that acts as the owner 'owner role'and then assign both my admin user and the flyway user to the owner role, and use ALTER scripts for each object to assign the object's owner to the owner role.
I missed the public schema, since that was auto-created when I created the database script manually. The public schema defaulted to my admin role rather than the shared owner role. So when the flyway user tried to assign public schema permissions to other roles, it didn't have the authority to do that.
An error was not thrown during flyway execution, however. Learn more. Asked 6 years, 7 months ago. Active 1 year, 3 months ago. Viewed 65k times. Ramprasad Ramprasad 6, 19 19 gold badges 60 60 silver badges bronze badges.

You need to grant access not only to the tables in the schema, but also to the schema itself. From the manual : By default, users cannot access any objects in schemas they do not own.
