亚马逊将向OpenAI投资500亿美元,建立多年战略伙伴关系

You might have noticed the row estimates (599 and 28,458) are lower than you'd expect for a 50-million-row table. The planner checks the actual physical file size. Our table is only 74 pages on disk, not the 123,513 we injected. Hence the planner scales reltuples down proportionally. The absolute numbers shrink, but the ratios between them stay correct, and it's the ratios that determine plan shape. When you use pg_dump --statistics-only in practice, you're typically restoring into a database with comparable data volume, so the estimates align naturally.

I say this even after using the Mix with the transmitter in lossless mode and the USB Audio cable. Both provide a small step up from conventional Bluetooth, but they can’t magically alter the Mix’s essential sound. I put these cans in the same league as the Beats Studio Pro and Sennheiser’s Accentum Plus, which, if you’ve ever heard these headphones, isn’t a knock against the Mix at all. One quick note on using the included analog cable when the Mix are powered off: It still works, but sound quality takes a huge hit. Consider it for emergency use only.
