The query made by the following code in FixupBlobRefs in pg_backup_db.c.
/* Can't use fmtId twice in one call... */
appendPQExpBuffer(tblQry,
"UPDATE %s SET %s =
%s.newOid"
,
tblName->data,
fmtId(attr),
BLOB_XREF_TABLE);
appendPQExpBuffer(tblQry,
" FROM %s WHERE
%s.oldOid = %s.%s",
BLOB_XREF_TABLE,
BLOB_XREF_TABLE,
tblName->data,
fmtId(attr));
