Fix building db service with pg_amqp and new base image

[yvanzo]

The official Docker images for Postgres updated their base image to more recent versions of Debian, breaking the compilation of pg_amqp.

This patch sets image variant, to prevent further breakage, and compilation flag, to address the three following errors:

The changes look sensible and correct, though I did not execute them (I assume you did already :)).
