Subject: Do not log subscription conninfo.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=448c4b3bfd0e302cc8d856560c33340594f863cc;p=thirdparty%2Fpostgresql.git

Do not log subscription conninfo.

Logging connection information, even at DEBUG1, creates unnecessary
risks. Remove the entire log message because it had no other useful
content.

Addresses finding 14 in report from linked discussion.
