I was rather surprised to find this code still present:
/*
* We set up the lockRelId in case anything tries to lock the dummy
* relation. Note that this is fairly bogus since relNode may be
* different from the relation's OID. It shouldn't really matter
though,
* since we are presumably running by ourselves and can't have any lock
* conflicts ...
*/
rel->rd_lockInfo.lockRelId.dbId = rnode.dbNode;
rel->rd_lockInfo.lockRelId.relId = rnode.relNode;
Seems quite unsafe in HS.
