I think what is happening is that postgres_fdw starts a transaction on
its connection as soon as it's asked to do something, and then the CREATE
TABLE executed on dblink's separate connection isn't visible to that
already-in-progress transaction.

That theory only holds up if you are running in serializable mode (which
postgres_fdw would then also use for its remote transaction).  Which you
didn't say, but it's hard to see how it'd fail otherwise.
