PostgreSQL is still vulnerable in the current quarterly branch since 2018-02-08. Why an MFH is not requested?
I had some weird conflicts when trying yo MFH those fixes the first time around, and didn't have time to look into it. The vulnerabilites in these CVE:s are really not relevent for a mainstream FreeBSD ports installation of postgresql, since it has to do with pg_upgrade, which is badly supported, and postgresql10-server, which is not the default version. Hence it has not been top priority. Best regards, Palle
