Yes, I was loading a large table. :-)
The filesystem with pg_xlog filled up, and the
backend (all backends) died abnormally. I can't
restart postmaster, either.
There are no stray IPC resources left allocated.
Is it OK to delete the files from pg_xlog? What
will be the result?
Will I be able to avoid this problem by splitting
the load data into multiple files?
Here's some information from the log:
