Create User Schema

[WCheyenneLu]

roles.sql

• create roles schema
• added RLS policies
  • Select: all
  • Insert: none
  • Update: none
  • Delete: none

roles (seeds)

• default, requestor, admin, superadmin, owner (0-4 accordingly)

user_roles function (private.can_assign_role(new_role_id int))

• function sets hierarchy of roles ( return true if the current user has the “owner” role and the new role is “superadmin”, “admin”, or “requestor” or if the current user has the “superadmin” role and the new role is “admin” or “requestor”etc.)

user_roles.sql

• create user roles schema
  • user_role_id, user_id, role_id
• add RLS policies
  • Select: all
  • Insert: private.can_assign_role(new_role_id int)
  • Update: none
  • Delete: private.can_assign_role(new_role_id int)

Note: user_role.sql is named user_role_x.sql since it needs to run after the function during migration (since it runs alphabetically)

Looks good!! 🤩 Additional edits:

• Added migration file with your changes
• Formatted using Prettier
• Renamed SQL files (put can_assign_role.sql into a functions folder)

Thank you for working on this over break! 🙏
