Fwd: not able to give usage access to public schema

[sekhar chandra <sekharclouddbengineer@xxxxxxxxx>]

I am not able to give usage permission to public schema. below are the steps.

Logged in as super user

created a new user as user1

grant usage on public to user1

command completed successfully , but verification statement showing he doesnt have usage permission.
SELECT rolname, has_schema_privilege(rolname, 'public', 'usage') from pg_roles;  

this is strage. what could go wrong.
