Hi Dear:
I am wondering is there transaction log facility in postgreg beside WAL.
I am using PostGres 7.0 which doesn't have WAL built in. If there is
another transaction logging facility, i had not to upgrade my PostGres.
Otherwise, I need to promote to my boss to upgrade the whole postgres.
Moreover, I am wondering is it possible to truncate the WAL log if I
drop a useless
table. It is no point to keep the log for a droped table.
Thank You
