ignore glibc specific code

[docteurklein]

I got pipelinedb to compile on alpine 🎈 🍸

here is the way I built it:

FROM alpine:edge as build

RUN apk add --no-cache postgresql-dev zeromq-dev curl make g++ libc-dev

#RUN curl -sL https://github.com/pipelinedb/pipelinedb/archive/1.0.0-6.tar.gz | tar xz
COPY pipelinedb-1.0.0-6 pipelinedb-1.0.0-6

RUN cd pipelinedb-1.0.0-6/ && \
    make USE_PGXS=1 && \
    make install

FROM alpine:edge

RUN apk add --no-cache postgresql zeromq-dev

COPY --from=build /usr/lib/postgresql/* /usr/lib/postgresql/
COPY --from=build /usr/share/postgresql/extension/* /usr/share/postgresql/extension/

EXPOSE 5432

ENV PGDATA=/var/lib/data/postgres
ARG LANG=en_US.utf8

RUN mkdir -p $PGDATA /run/postgresql /etc/postgres && \
    chown postgres:postgres $PGDATA /run/postgresql /etc/postgres

USER postgres

RUN pg_ctl initdb -o "--locale=$LANG"

CMD ["postgres",  "-c", "config_file=/etc/postgres.conf"]

COPY hba.conf /etc/postgres.hba
COPY postgres.conf /etc/postgres.conf

The server is booting, so i'm going to sleep now :)

found this on #1773 (comment)
no idea what I'm doing

[docteurklein]

I think this breaks the wanted static linking of libzmq in the extension, as I had to install zeromq-dev in the runtime env.

[docteurklein]

again, not sure if that's even a good idea; found a similar fix in https://github.com/PowerDNS/pdns/pull/1958/files

[docteurklein]

maybe there is a way to find the "else" version for musl ?

[docteurklein]

see #1692

[docteurklein]

see #1578

Excellent, many thanks for this solution and the edits, I wish there was an alpine-ready version out of the box.

Thanks for this work, @docteurklein!
It was really helpful for my docker image https://github.com/binakot/PostgreSQL-TimescaleDB-PipelineDB. I know that just disable backtrace is not the solution, but at least it works. This was enough https://github.com/binakot/PostgreSQL-TimescaleDB-PipelineDB/blob/master/Dockerfile#L75
