正如在这个问题中所问的那样，我尝试将 plpython3 扩展添加到我的 timescaledb/postgres（基于 linux alpine）图像中。

不幸的是，接受的答案似乎不再起作用。

我用以下代码更新了 dockerfile，但没有任何运气：

RUN apk update \
&& apk add --no-cache --virtual .build-deps build-base gcc postgresql-plpython3 \
&& ln -s /usr/lib/postgresql/plpython3.so /usr/local/lib/postgresql/plpython3.so \
&& ln -s /usr/share/postgresql/extension/plpython3u.control /usr/local/share/postgresql/extension/plpython3u.control \
&& ln -s /usr/share/postgresql/extension/plpython3u--1.0.sql /usr/local/share/postgresql/extension/plpython3u--1.0.sql \
&& ln -s /usr/share/postgresql/extension/plpython3u--unpackaged--1.0.sql /usr/local/share/postgresql/extension/plpython3u--unpackaged--1.0.sql

当我运行命令时，CREATE EXTENSION plpython3u; 我收到以下错误：

Error in query (7): ERROR: could not load library "/usr/local/lib/postgresql/plpython3.so": Error relocating /usr/local/lib/postgresql/plpython3.so: pg_vsnprintf: symbol not found

关于如何解决这个问题的任何想法？

这是用于测试目的的完整 dockerfile：

FROM timescale/timescaledb:1.7.5-pg11

# Monitoring tools
RUN apk update \
    && apk add --no-cache --virtual .build-deps build-base gcc postgresql-plpython3 \
    && ln -s /usr/lib/postgresql/plpython3.so /usr/local/lib/postgresql/plpython3.so \
    && ln -s /usr/share/postgresql/extension/plpython3u.control /usr/local/share/postgresql/extension/plpython3u.control \
    && ln -s /usr/share/postgresql/extension/plpython3u--1.0.sql /usr/local/share/postgresql/extension/plpython3u--1.0.sql \
    && ln -s /usr/share/postgresql/extension/plpython3u--unpackaged--1.0.sql /usr/local/share/postgresql/extension/plpython3u--unpackaged--1.0.sql

CMD ["postgres"]

谢谢你的帮助
