Hi,
Impressive stuff!
Apparently this depends on a newer, yet-to-be-published version of the
pglogical_output patch:
.../contrib/pglogical/pglogical_hooks.c: In function
‘pglogical_row_filter_hook’:
.../contrib/pglogical/pglogical_hooks.c:173:35: error: ‘struct
PGLogicalRowFilterArgs’ has no member named ‘change’
HeapTuple tup = &rowfilter_args->change->data.tp.newtuple->tuple;
^
It currently doesn't do multi-master or automatic DDL. I think DDL should

I wish could find the time to get back to this patch. I didn't check it in
quite a while...

This is prone to errors when connstring is specified in URI format. A
workaround is provided in this commit for
