I ran into a very strange disappearance of a postgresql data file.
The environment:
Windows XP professional
select version();
PostgreSQL 8.0.1 on i686-pc-mingw32, compiled by GCC gcc.exe (GCC)
3.4.2(mingw-special)
All datafiles are within c:\ghum\data
that part of the harddrive is only accessable to user account postgres (=3D
the one running the service) and Administrator.
the logentries:
postgresql-2005-11-21_080758.log
2005-11-21 08:08:05 LOG: startup process (PID 1220) exited with unexpected

... and on and on and on...
My checking showed that... within directory data/base/17253 there is indeed
no file named 43471; but ones named 43470,43472,43473 .....
Additional Information: that is a laptop-computer, and it is quite possible
that it was restarted between 8:08 and 8:40 this morning.
But ... I see no line mentioning a "killing of a file". Can I do something
more to find out WHY this file disappeared? (and esp. make sure that no more
files disappear :( )
