This often works but it also fails far too often (in my hands). I
That being said, I am so far having problems reproducing this on my
test
machine(s) so no idea what causes it yet.
A few extra bits:
- I have repeated this now on three different machines (debian 7, 8,
centos6; one a pretty big server); there is always failure within a few
tries of that test program (i.e. pgbench_derail2.sh, with the above 5
patches).
- I have also tried to go back to an older version of logrep: running
with 2 instances with only the first four patches (i.e., leaving out the
support-for-existing-data patch). With only those 4, the logical
replication is solid. (a quick 25x repetition of a (very similar) test
program is 100% successful). So the problem is likely somehow in that
last 5th patch.
- A 25x repetition of a test on a master + replica 5-patch server yields
13 ok, 12 NOK.
- Is the 'make check' FAILED test 'object_addess' unrelated? (Can you
at least reproduce that failed test?)
Maybe add this to the 10 Open Items list?
https://wiki.postgresql.org/wiki/PostgreSQL_10_Open_Items
It may garner a bit more attention.
