psql:符号查找错误:psql:未定义符号:PQsetErrorContextVisibility

psql: symbol lookup error: psql: undefined symbol: PQsetErrorContextVisibility

这意味着您的 psql 副本正在 libpq.so 中查找动态符号，而该符号在您的路径中没有.

That means your copy of psql is looking for a dynamic symbol in libpq.so which the version in your path does not have.

您有 psql 的自定义编译版本吗?而且，如果是这样，则必须针对9.6提供的较新的libpq构建它.

Do you have a custom compiled version of psql? And, if so, you'll have to build it against the newer libpq that 9.6 provides.
