title: PostgreSQL Error [42501]: ERROR: must be owner of relation table
body: <p>I am maintaining a database 'db' in which there are around 100 tables.I have one super user 'A' and 'A' is the owner of all tables. How can I give Alter permission to new user 'B' specific to single table without inheriting all permissions from 'A'. </p>
  
  <p>I tried by providing <code>Grant A to B;</code>. This Grant option given all permissions from 'A' to 'B'. I want above scenario to restrict to one particular table. 
  Is this possible? </p>
