I've tried the different wal_sync_method settings and nothing seems to work.
I don't know if it matters, but I'm running PostgreSQL on an XP Embedded
system. Initially, I had most of my tables installed in the default
location, c:\program files\postgresql\8.3\data, on compact flash -- which is
protected with Enhanced Write Filter (EWF) and uses Hibernate Once Resume
Many (HORM). My log tables were mapped to a solid state drive using
tablespace definitions. This configuration didn't seem to work very well so
I ended up installing everything to the solid state drive that isn't being
protected with EWF and is not part of the hibernated image. When I
disconnect power from the system I'd like to see recently added records show
up on the next boot. If I perform a clean shutdown of the system the records
written to disk.
