That probably represents some non-Postgres bit of code deciding to bleat
to stdout or stderr. The logging-collector mechanism is designed to catch
such output coming from a backend process, but it can't stick a
log_line_prefix on it.
What exactly is bleating, I can't say. A quick grep confirms that there
is no such string in the Postgres sources, but I dunno about PostGIS.
If you've got any code in plperl, plpython, etc, the culprit might lurk
somewhere there. glibc might even be to blame, though I don't think it
ordinarily prints error messages.
