In what cases should I use UUID as primary key in Django models

What are advantages and disadvantages of UUID field?

When should I use it as a primary key? When should I use default primary key?

My table has many rows. Is it possible that max value of default primary key will be exceeded?

I use PostgreSQL.

Primary Key -

It is an auto-increment unique key which is created by database engine when we create a new record each time to the table.

UUID -

It is unique too but it is unique in "the whole universe", not guaranteed unique but practically unique. Like when we want create a ticket based environment to solve customer issues then we must generate a ticket_id by UUID(because its unique and it is combination of random numbers).
