Pagination is not compatible with UUID primary keys

[djmaze]

When using PostgreSQL and having a UUID type column as a primary key, the pagination might produce inconsistent results during dumping. UUIDs are not incrementing, but the pagination sorts by "id". That means when new records are inserted while the table is being dumped, they might appear randomly in pages, so pages might overlap. This leads to missing or duplicate records in the output.
