Tom Lane 80559fa9e9 I found a corner case in which it is possible for RI_FKey_check's call ... of HeapTupleSatisfiesItself() to trigger a hint-bit update on the tuple: if the row was updated or deleted by a subtransaction of my own transaction that was later rolled back. This cannot occur in pre-8.0 of course, so the hint-bit patch applied a couple weeks ago is OK for existing releases. But for 8.0 it seems we had better fix things so that RI_FKey_check can pass the correct buffer number to HeapTupleSatisfiesItself. Accordingly, add fields to the TriggerData struct to carry the buffer ID(s) for the old and new tuple(s). There are other possible solutions but this one seems cleanest; it will allow other AFTER-trigger functions to safely do tqual.c calls if they want to. Put new fields at end of struct so that there is no API breakage.		2004-10-30 20:53:06 +00:00
