non-dirty shared
buffers appears to be insufficient", as this makes the language simpler and
avoids introducing another new term (non-dirty, which means the same as
clean).
Thanks again, Chris.

Hi all,
Thanks Thomas.
When the bgwriter flushes (cleans) a dirty Postgres buffer, it generates a
write() syscall of its own, which I think must increase the number of dirty
cache buffers in the Linux kernel (temporarily, until it actually flushes
those cache buffers to disk). Therefore it tempor
Hi all,
We do document the range for some parameters:
- bgwriter_flush_after: "The valid range is between 0, which disables
forced writeback, and 2MB."
- effective_io_concurrency (integer): "The allowed range is 1 to 1000,
or zero to disable issuance of asynchronous I/O requests."
