Update of /home/projects/pgsql/cvsroot/pgsql/src/backend/storage/buffer
from hub.org:/home/projects/pgsql/tmp/cvs-serv9419
Modified Files:
bufmgr.c
----------------------------- Log Message -----------------------------
Fix incorrect logic for clearing BufferDirtiedByMe in ReleaseRelationBuffers
and DropBuffers. Formerly we cleared the flag for each buffer currently
belonging to the target rel or database, but that's completely wrong!
Must look at BufferTagLastDirtied to see whether the BufferDirtiedByMe
flag is relevant to target rel or not; this is *independent* of the
current contents of the buffer. Vadim spotted this problem, but his
fix was only partially correct...
