Hi hackers,
While resuming the work on refilenode stats (mentioned in [1] but did not share
the patch yet), I realized that my current POC patch is buggy enough to produce
things like:
024-05-14 09:51:14.783 UTC [1788714] FATAL: can only drop stats once
While the CONTEXT provides the list of dropped stats:
2024-05-14 09:51:14.783 UTC [1788714] CONTEXT: WAL redo at 0/D75F478 for Transaction/ABORT: 2024-05-14
09:51:14.782223+00;dropped stats: 2/16384/27512/0 2/16384/27515/0 2/16384/27516/0
It's not clear which one generates the error (don't pay attention to the actual
values, the issue comes from the new refilenode stats that I removed from the
output).
Attached a tiny patch to report the stat that generates the error. The patch uses
errdetail_internal() as the extra details don't seem to be useful to average
users.

Looking forward to your feedback,
