This will list all table-level privileges assigned to the user.Review the Grant Command: Verify the syntax and object names in the GRANT statement that caused the error. Ensure that the object (table, database, etc.) exists and the spelling is correct.Check Object Existence: Ensure that the object you are trying to grant privileges on exists. For a table, you can check its existence with:SELECT * FROM information_schema.tables WHERE table_name = 'your_table_name';Replace 'your_table_name' with the name of the table you are working with.Verify Database Existence: If the grant operation was related to a database, ensure the database exists with:\lThis command lists all databases in the Postgres server. Make sure the database you are trying to operate on is listed.Consult Postgres Documentation: If you're unsure about the correct syntax for the GRANT command or the privileges you need to check, briefly consult the Postgres documentation related to granting privileges.Check for Read-Only Transaction: If you're inside a transaction block, ensure it's not set to read-only.
