Is this still in the plan?

[vincentsarago]

@francbartoli Yes

We started a PR over #236 but we're on hold while we look for customers to finance the end of development.

[francbartoli]

Do you accept contributions to that PR?

[vincentsarago]

@francbartoli we do 🙏

The next think we want/need for this project is to replace buildpg. I'll ask @bitner to write a ticket about this 🙏
