agentzh forked eval module and made it work with regular subrequests (so
also with ngx_postgres):
Alternatively, you could use ngx.location.capture() feature from ngx_lua
module to make the subrequests to PostgreSQL location.
I also believe that the first test case from
https://github.com/FRiCKLE/ngx_postgres/blob/master/t/eval.t might be of
interest to you.
