Hi,

Recently I got this error while the database was starting up. :

FATAL 2: XLogWrite: writerequest is past end of log

And the database did not startup, and finally I had to do a
pg_resetxlog. I tried going through the code which gave
this error but I was unable to comprehend much.

Could anyone tell me how exactly this error is caused. Also I would like
to know whether there is any detail
documentation about the WAL implemenation (also pg_resetxlog
implemenation) of postgres.

Thanks in advance.
Regards,
Aniket
