The use of pg_atoi() for parsing a string into an Oid fails for values larger than INT32_MAX, since OIDs are unsigned. Instead, use atooid(). While this has less error checking, the contents of the data directory are expected to be trustworthy, so we don't need to go out of our way to do full error checking.
