Hi Julien!
I eventually gave up and went back to pg14. same problem, (big clue) but
this time initdb gave me an error "could not link" and "operation not
permitted" just before the unhelpful wal error.
I had posted the logs from the postgres server. Do you mean something
other by 'full postgres log'? Very interested to know if I missed something.
You are correct, 'quickest way' was for a test server that was not
stable already. Not something you would want to do in production. Thank
you for pointing that out. I'd hate to have someone reset their wal from
my recommendation.
Best Regards,
Justin Tocci
