previous pgdg postgresql 9.2.10 ubuntu 1204 amd64 packages needed

Hi!

I am thankful https://wiki.postgresql.org/wiki/Apt user, being now at
9.2.13 (on Ubuntu 12.04 amd64) i would like to test something how it
runs on previous 9.2.10 version. Browsing
http://apt.postgresql.org/pub/repos/apt/pool/9.2/p/postgresql-9.2/ i
dont see this older version and in itself this is normal Debian-like
repository behavior i think. Is it still possible to have access to
versions than have been previously on PGDG apt repository? It is not
important to have access like snapshot.debian.org, just .deb files is
quite enough and i can generate local file system based repository i
believe.

I imaging as an alternative would be to say 'git clone' and work with
proper branches and build routine. If older version is not available i
would be happy if somebody could give me a brief instructions how to
build 9.2.10 (postgresql-9.2 and
postgresql-9.2-plproxy actually) .deb packages (i am generally familiar
with deb-src building).


Best regards,

Imre
