I've uploaded also the script output ( CASCADE traces ) :
http://strk.keybit.net/tmp/could_not_open_relation.sql
http://strk.keybit.net/tmp/could_not_open_relation.log
And realized that the relation oid is the one first
requested for deletion. Ie:
DROP TABLE XXX CASCADE;
..
ERROR: could not open relation with OID XXX:regclass::oid
I've found two ways to avoid the error:
1. Perform the DROP TABLE outside the transaction triggering its creation
2. Avoiding population of the table being dropped (the AddEdge call)
Note that the 'edge_data' table has a foreign key to itself, and the
constraint is initially deferred (may have a role here, I guess ?)
"next_left_edge_exists" FOREIGN KEY (abs_next_left_edge)
REFERENCES.edge_data(edge_id)
DEFERRABLE
INITIALLY DEFERRED,
"next_right_edge_exists" FOREIGN KEY (abs_next_right_edge)
REFERENCES edge_data(edge_id)
DEFERRABLE
INITIALLY DEFERRED
