Possible memory leak/memory issue in pg_dump

While browsing the code, "pg_dump.c" the following block *appears* to
be problematic. Additionally, there *appears* to be a malloc without a
free (return or assignment) in the function "getBlobs(Archive *AH)"
(pg_dump.c lines 2169 thru 2188 v9.1.4).

/*
* Each large object has its own BLOB archive entry.
*/
binfo = (BlobInfo *) malloc(ntups * sizeof(BlobInfo));

for (i = 0; i < ntups; i++)
{
binfo[i].dobj.objType = DO_BLOB;
binfo[i].dobj.catId.tableoid = LargeObjectRelationId;
binfo[i].dobj.catId.oid = atooid(PQgetvalue(res, i, 0));
AssignDumpId(&binfo[i].dobj);

binfo[i].dobj.name = strdup(PQgetvalue(res, i, 0));
if (!PQgetisnull(res, i, 1))
binfo[i].rolname = strdup(PQgetvalue(res, i, 1));
else
binfo[i].rolname = "";
if (!PQgetisnull(res, i, 2))
binfo[i].blobacl = strdup(PQgetvalue(res, i, 2));
else
binfo[i].blobacl = NULL;
}
