I was just looking at the Xversion test failure on crake (which has the log
entry below) when I saw your email.

pg_dump: error: query failed: ERROR: column "publish_gencols_none" does not exist
LINE 1: ...elete, false AS pubtruncate, false AS pubviaroot, PUBLISH_GE...
^
pg_dump: detail: Query was: SELECT p.tableoid, p.oid, p.pubname, p.pubowner, p.puballtables, p.pubinsert, p.pubupdate, p.pubdelete, false AS pubtruncate, false AS pubviaroot, PUBLISH_GENCOLS_NONE AS pubgencols_type FROM pg_publication p
pg_dumpall: error: pg_dump failed on database "template1", exiting

Your patch seems like a reasonable fix.
