Question

我在Linux上使用pgAdmin4，但是由于某种原因，我不再能够列出存储的连接。它在全新安装上工作了几天，然后在重新启动后突然停止了工作（事先未完成安装/更新）。我在多台具有类似设置的计算机上体验到了这一点。

系统信息：

内核：4.19.34-1-MANJARO
发行：Manjaro
Python 3.7.3

当我尝试列出存储的连接时，~/.pgadmin/pgadmin4.log中将显示以下内容：

Traceback (most recent call last):
  File "/usr/lib/python3.7/site-packages/flask/app.py", line 1813, in full_dispatch_request
    rv = self.dispatch_request()

    in_recovery, wal_paused = recovery_state(conn, manager.version)

    status, result = connection.execute_dict(recovery_check_sql)

    desc.to_dict() for desc in cur.ordered_description()
  File "/usr/lib/pgadmin4/web/pgadmin/utils/driver/psycopg2/connection.py", line 1202, in <listcomp>

    ores = OrderedDict(self.orig_col._asdict())
AttributeError: 'psycopg2.extensions.Column' object has no attribute '_asdict'

任何想法在这里有什么问题吗？

这是由于新版psycopg2模块导致的错误，已在pgAdmin4 v4.5的最新版本中修复，请升级至最新版本。
