Someone pointed out this morning that we still have this in our docs:
"It is advantageous if the WAL is located on a different disk from the main database files. This can be achieved by moving the pg_wal directory to another location (while the server is shut down, of course) and creating a symbolic link from the original location in the main data directory to the new location."
This is not as important as it used to be, and I would even hazard to say that we should not be encouraging it. There are still use cases for doing so, yes, but "advantageous" is too much. I played with some wording, but at the end of the day, I am thinking that we simply remove this paragraph entirely.
Cheers,
Greg
