Hi Thomas,
You might have missed a spot to initialize SERIALIZABLE_XACT->pgprocno in
InitPredicateLocks(), so:
+ PredXact->OldCommittedSxact->pgprocno = INVALID_PGPROCNO;
Slightly tangential: we should add a comment to PGPROC.pgprocno, for more
immediate understandability:
+ int pgprocno; /* index of this PGPROC in ProcGlobal->allProcs */
Also, why don't we take the opportunity to get rid of SERIALIZABLEXACT->pid? We
took a stab. Attached is v2 of your patch with these changes.
Regards,
Ashwin and Deep
