I don't think that's possible.
If it were not the size of the statement itself, but the number of parameters, you could set
"log_parameter_max_length" so that only a couple of them are displayed, but the statement
itself is logged in its entirety.
You could experiment with syslog logging and set "syslog_split_messages = off".
Syslog will skip logging long lines, but the limit cannot be configured and is
probably shorter than you want.
