Well, when you do a DROP TABLE and there's no table with the name you
give, the system is right in giving you a "table foo does not exist".
However, when you create a foreign key to a table that doesn't exist
(because you are creating it further down in your script), the system
doesn't know it is a table (it could be a view, for example). So it
falls back to using the more general term, "relation".
"Relation" means, in Postgres terms, "anything that can have a pg_class
entry". This means system tables and views, regular tables and views,
indexes, sequences, TOAST tables and special relations like pg_xactlock
if I'm not mistaken.
