[GTALUG] Debian postgresql security advisory

[Giles Orr]

Debian issued a security advisory for postgresql today:
https://www.debian.org/security/2016/dsa-3646 .  So I want to upgrade
my pgsql install on stable.  The advisory says "these problems have
been fixed in version 9.4.9-0+deb8u1."  I upgraded, and found myself
with version 9.4+165+deb8u1.  And this has me very confused,
particularly since the online database (
https://packages.debian.org/search?searchon=sourcenames&keywords=postgresql-9.4
) shows the jessie version recommended by the advisory.  If I run
"lsb_release -c" I get "Codename:    jessie" in response.  The
sources.list is basic but complete(?):

deb http://http.debian.net/debian jessie main
deb http://security.debian.org/ jessie/updates main
deb http://http.debian.net/debian jessie-updates main

(I've left out the deb-src statements.)

First, why the discrepancy?  Second, where do I go to find out what
went into the current package?  ie. is there a place to look that will
say "9.4+165+deb8u1 was compiled for X reason?"

I installed a new virtual machine from a fresh download of
debian-8.5.0-amd64-netinst.iso.  A final "apt-get update ; apt-get
dist-upgrade" finds me at the same 9.4+165+deb8u1.
