The partition MERGE (1adf16b8f) and SPLIT (87c21bb94) v17 patches introduced
createPartitionTable() with this code:

    createStmt->relation = newPartName;
...
    wrapper->utilityStmt = (Node *) createStmt;
...
    ProcessUtility(wrapper,
...
    newRel = table_openrv(newPartName, NoLock);

This breaks from the CVE-2014-0062 (commit 5f17304) principle of not repeating
name lookups.  The attached demo uses this defect to make one partition have
two parents.
