Fix two bugs in setting the vm bit of empty pages. Use a critical section when setting the all-visible flag on an empty page, and WAL-logging it. log_newpage_buffer() contains an assertion that it must be called inside a critical section, and it's the right thing to do when modifying a buffer anyway.
Also, the page should be marked dirty before calling log_newpage_buffer(), per the comment in log_newpage_buffer() and src/backend/access/transam/README. Patch by Andres Freund, in response to my report. Backpatch to 9.2, like the patch that introduced these bugs (a6370fd9).
