Depends on the implementation, I guess, but the point is that there's a
bazillion network-based filesystems with different tradeoffs out there
already. It seems unlikely that you could outperform them with something
built into PostgreSQL.

To put it other way, if you built network-based storage into PostgreSQL,
what PostgreSQL-specific knowledge could you take advanage of to make it
more performant/reliable? If there isn't any, I don't see the point.
