Put a CHECK_FOR_INTERRUPTS call into the loops that try to find a unique new
OID or new relfilenode. If the existing OIDs are sufficiently denselypopulated, this could take a long time (perhaps even be an infinite loop),so it seems wise to allow the system to respond to a cancel interrupt here.Per a gripe from Jacky Leng.Backpatch as far as 8.1. Older versions just fail on OID collision,instead of looping.
