That is not an "error".

This is one out of a group of three related triggers that ancient
Postgres versions used to use to implement foreign key constraints.
(Actually, modern versions still use related triggers, but they're
a bit better hidden now --- you shouldn't see them in pg_dump output,
for sure.)
The message is telling you that the system is waiting for the other two
matching trigger definitions so that it will have enough information to
create a regular FOREIGN KEY constraint.
If you are doing this as part of loading an old dump file, just ignore
the notice and keep going; everything should be fine. If you are doing
this manually, maybe you had better explain why.
