I don't have another solution that can be pushed into v17. I understand
the risks raised so far, so I'm okay with just pushing the "fast_forward" patch.
It might be helpful to add a note to the summarize_wal documentation,
for example, "summarize_wal can be enabled after startup with wal_level =
minimal,
but WAL generated at this level won't be summarized."?
Here is v5. This version differs from v4 in that it updates the
documentation for summarize_wal and pg_get_wal_summarizer_state(). The
previous version made no documentation changes.
Thanks for updating the patch! It looks good to me, except for one minor detail.
+ reaches WAL not generated under <literal>wal_level=minimal</literal>,
+ it will resume writing summaries to disk.
"WAL not generated under wal_level=minimal" sounds a bit confusing??
How about "WAL generated while wal_level is replica or higher" instead?
