toast operations while locking a buffer
Started by Hiroshi Inoueabout 25 years ago2 messages
Hi all
I see heap_tuple_toast_attrs() calls in heapam.c.
When they are called from heap_update/delete()
,a buffer is locked.
OTOH heap_tuple_toast_attrs() calls heap_open(..,
.., RowExclusiveLock). Hmm,try to acquire a
RowExclusiveLock while locking a buffer.
Is there no problem ?
Regards.

Hm. Seems like it would be better to do the tuple toasting before
we lock the target buffer...
