I'm not sure it's fixed. I am attempting a pg_upgrade from 9.2.8 to 9.3.5 and it dies like so:
(...many relations restoring successfully snipped...) pg_restore: creating SEQUENCE address_address_id_seq pg_restore: [archiver (db)] Error while PROCESSING TOC: pg_restore: [archiver (db)] Error from TOC entry 1410; 1259 17670 SEQUENCE address_address_id_seq javaprod pg_restore: [archiver (db)] could not execute query: ERROR: could not create file "base/16414/17670": File exists Inspecting a copy of the source cluster, OID 17670 does indeed correspond to address_address_id_seq, but inspecting the partially-upgraded cluster that OID is taken by pg_toast_202359_index. Again conferring with a copy of the source (9.2.8) cluster, the relation corresponding to filenode 202359 does not have a toast table. (I know pg-hackers isn't the right place to discuss admin issues, but this thread is the only evidence of this bug I can find. If anyone can suggest a workaround I would be infinitely grateful.)
