It looks to me like this was an attempt to replicate from 15beta1 to
15beta2, which would fail because commit fd0b9dceb imagines that any
server reporting version >= 15 will have pg_publication_tables.attnames,
even though that column was not there in beta1.
I bitched about the ill-timing of that schema change at the time
but was outvoted. At this point I think it's water over the dam.
We could perhaps change that test in fetch_table_list(), but it'd
require access to the source server's catversion, which I don't think
is readily available. In any case, by the time we could provide a fix
it'd be useless to testers of beta1; they'd have updated already by
some other method.
