I'm running Packetbeat 5.0.0~alpha1, and getting a lot of entries like the following in syslog:
Apr 28 16:04:08 cat-pg92 /usr/bin/packetbeat: parse.go:531: Pgsql invalid column_length=4294967295, buffer_length=234, i=5
Apr 28 16:04:08 cat-pg92 /usr/bin/packetbeat: parse.go:531: Pgsql invalid column_length=4294967295, buffer_length=558, i=11
I can't find any reference to this message online, other than in the source on github. I'm not sure if this is an issue with Postgres or Packetbeat. This is a new error since upgrading Packetbeat from 1.1.2, however the previous version was giving me "Slice bounds out of range" errors as per this thread.
Config is as follows:
interfaces: device: any protocols: pgsql: ports:  output: logstash: hosts: ["ingress1:10514", "ingress2:10514"] tls: certificate_authorities: ["/etc/ssl/certs/beats-ca.pem"] insecure: false
System is Ubuntu 12.04.5
