gitlab failing caouse can't find postgresql 9.4

[robe]

I was looking at why gitlab is failing on recent tests. It's showing this.

This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'postgresql-9.4' has no installation candidate
E: Unable to locate package postgresql-server-dev-9.4
E: Couldn't find any package by glob 'postgresql-server-dev-9.4'
E: Couldn't find any package by regex 'postgresql-server-dev-9.4'
E: Unable to locate package libjson0-dev
ERROR: Job failed: exit code 1

I created a "gitlab-ci" branch on gitlab to try at fixing this: ​https://gitlab.com/postgis/postgis/merge_requests/8

Ok this is scary:

$ apt-cache search postgresql
libpq-dev - header files for libpq5 (PostgreSQL library)
libpq5 - PostgreSQL C client library

Comes from ​https://gitlab.com/postgis/postgis/-/jobs/53520863

Time to switch gitlab-ci to Docker too ?

After an apt-get update I see PostgreSQL-9.6 is available. More packages changed names though, so that branch needs more love.
