当我在docker中运行bash文件时，我计划通过一个服务器A运行一些psql命令到另一个具有postgresql数据库的服务器（数据库服务器），但是它说
[ERROR] [ trapError] An unexpected error occured at line 141 ./functions.sh`
此bash文件的详细信息是：
executeSql() {
local tmp="/tmp/executeSql"
ssh ${DBUSERHOST} "sudo -u postgres psql -c \"${SQL}\" -d studenta" > ${tmp} 2>&1
ST=$?
if [ "${ST}" != "0" ]; then
ERROR "Failed to execute sql query"
cat "${tmp}" >> "${LOGFILE}"
exit 10
fi
}
第141行对应
ssh ${DBUSERHOST} "sudo -u postgres psql -c \"${SQL}\" -d studenta" > ${tmp} 2>&1
当我检查PostgreSQL容器中的日志时，它显示如下：

所以我想在容器A中，该过程在运行psql命令期间停止了，这导致数据库服务器意外关闭，我怀疑这是某个超时连接，但是不确定...
日志中有一个快速关机，当我运行bash时，它立即退出并出现错误，如本page中所述，可能是PostgreSQL中启用了一些无人值守的安全更新，仍在检查原因... < / p>
另外，问题在于它仅显示了trapError而没有进一步的细节，因此很难找出原因，请问是否有任何解决方案或任何方法可以解决此问题？
