Testing logical replication, with the following patches on top of
yesterday's master:

0001-Reserve-global-xmin-for-create-slot-snasphot-export.patch +
0002-Don-t-use-on-disk-snapshots-for-snapshot-export-in-l.patch+
0003-Prevent-snapshot-builder-xmin-from-going-backwards.patch +
0004-Fix-xl_running_xacts-usage-in-snapshot-builder.patch +
0005-Skip-unnecessary-snapshot-builds.patch

Is applying that patch set is still correct?

It builds fine, but when I run the old pbench-over-logical-replication
test I get:

TRAP: FailedAssertion("!(entry->trans == ((void *)0))", File:
"pgstat.c", Line: 828)

reliably (often within a minute).

The test itself does not fail, at least not that I saw (but I only ran a
few).

thanks,

Erik Rijkers
