The stack trace does look the same, but do you have the same triggering
condition we identified (that is, fairly wide column values in the
subscriber table that are not getting replaced during a
logical-replication update? or possibly dropped columns in the
subscriber table?)

How quickly downstream packages appear isn't entirely under our
control, though.

Couldn't say, but with most packaging systems it's relatively simple
to rebuild a given package with a custom patch or two added. (If
memory serves, with Debian's system you don't even have to modify
any files, just add the patch into the relevant subdirectory.)
That's a skill worth acquiring if you deal with open source a lot.

FWIW, I do know that Christoph does test builds for Debian and Ubuntu
on a pretty regular basis, because he complains when things break ;-).
Whether he makes those builds widely available, though, I don't know.
