In the context of PostgreSQL 7.4, running over Linux Suse 9.0, I have some
doubts that wanted to evacuate:
In which processes impacts the property fsync?
Which can be the problem to use fsync in false?
When use fsync = false, the effective recording of the data in disk is done
for criteria of the operating system, ¿ Is exact?
Considering fsync = false, checkpoint_timeout=300.
It given a crash of the operating system, after normally db shutdown. At db
startup, there was corruption of data and a pg_resetlogwas done.
It is possible to lose data changed previous to last checkpoint ?
Thanks,
Fabio
