So I googled and tried the solution listed in the linked thread.
I did a "start transaction" via psql on the master but I continued to get the error.
Wondered if there was more to it than that.

I don't see why dblink would be the special thing. I think what you
want is to hold a transaction open on the master so that the WAL can't
get recycled. At least, that's what I understood from the post. I
haven't actually tried it yet, but to me it sounded like it ought to
work.
