So the full log files correspond to the server log file, right? What
process is filling the logs? (You can tell by adding a %p to
log_line_prefix in postgresql.conf, if it's not there already).

Is the table a FDW table or something otherwise funny? Please give more
details; also about the underlying platform (is this a non-Intel
dinosaur or something?)
