the offnum of LOCKTAG I gather indicates which row (tuple) is being locked
in a row level locking. But when I lock 2 diffrent rows of a table, offset
for both is 0. and also offset is 0 if i take a table lock on the same
table. (blkno is the same for all three locks)..shouldnt the OffsetNumber
offnum be different for each individual row lociked? if not, then what field
of LOCKTAG recognizes each individual row (tuple) locked?
thanks!
