Keep postgres static libraries in Alpine images

[bkmit]

Do not remove static postgres libraries from Alpine based images.
This add near 1.4MB to image size, but allow to complie some extentions
like repmgr without errors

Would it be possible to give a simple example Dockerfile that fails to build now that works after this change?

Thanks!

I had to change RUN git clone --branch "${REPMGR_VERSION}" https://github.com/2ndQuadrant/repmgr to include /tmp/repmgr at the end (to declare the target directory), but I've verified that this does indeed enable that! 👍

Have updated PR to not delete empty lines

Nice work, thank you! LGTM 👍
