I don't know if we are making progress but I am getting a different
error now :-)
I did the dd command again this time with count=18. Now when I try to
delete the tuple I get this:
dbmail2=# delete from messageblks where oid = 2916427;
ERROR: attempted to delete invisible tuple
The Postmaster log has this to say:
ERROR: XX000: attempted to delete invisible tuple
LOCATION: heap_delete, heapam.c:1258
Thanks again for the help.
