Re: Re: Assertion failure in WAL summarizer

Hi,

Beyond confirming v4 applies and the suites pass, I checked that each new
test
actually reproduces its failure on unpatched master -- i.e. with the three
test
files in place but the code changes reverted:

- pg_walsummary/t/
https://www.google.com/url?q=http://004_promote_past_target.pl&source=gmail&ust=1794456004508000&sa=E:
fails at "the summarizer does not
read past replay", and pg_ctl promote then exits 1 -- the post-promotion
path
this series fixes.
- pg_combinebackup/t/
https://www.google.com/url?q=http://015_summary_past_switch.pl&source=gmail&ust=1794456004508000&sa=E:
the same "reads past replay"
failure on the standby, and promote exits 1.
- pg_combinebackup/t/
https://www.google.com/url?q=http://016_truncation_after_target.pl&source=gmail&ust=1794456004508000&sa=E:
the server terminates
abnormally during the post-promotion incremental backup
(pg_basebackup: server closed the connection unexpectedly).

With all three patches applied, every test passes (pg_combinebackup 147/147,
pg_walsummary 34/34, on an assert-enabled build). So the tests reproduce the
reported failures -- including the server crash on the
truncation-after-target
path -- and the series resolves them.

Sai Pranav
