You're very welcome to add support for OpenResty/ngx_lua based
backends :) You should observe much better performance than PHP and
Node.js.

See https://github.com/agentzh/encrypted-session-nginx-module
But given that ngx_lua and your Lua code is running directly within
the Nginx server, it's fine to do this in Lua as well.

You can do this by pure nginx.conf scripting, but use of Lua in your
nginx server is recommended.

Yes, you can use the ngx_encrypted_session module with the ngx_postgres module.
When I was working on the nginx-based web service APIs for the
lz.taobao.com site a few years ago I also tried to use pure nginx.conf
scripting for complicated things. But quickly I found it really hard
to maintain and debug. That's why we created the ngx_lua module to
embed the Lua/LuaJIT engine into the nginx core. Since then the world
is clean and fast.
