I wouldn't recommend deleting *any* files manually --- unless you find
core files or old files underneath a pgsql_tmp subdirectory. Those you
could zap at little risk.
The best approach is to free up a small amount of space elsewhere,
enough so you can get through a CHECKPOINT without failing. The
checkpoint will hopefully free up some space in pg_xlog. After that you
can look at dropping tables you don't need any more, VACUUM FULL, etc.
