PGAdmin:未连接到服务器或与服务器的连接已关闭 [英] PGAdmin: Not connected to the server or the connection to the server has been closed

问题描述

我在使用postgreSQL时遇到了这个问题，当我对任何内容进行简单查询(CRUD)时，有时它都有效并且几乎总是显示此消息:

i got this problem with postgreSQL, when i do a simple query of anything (CRUD), sometimes it works and almost always shows this message:

未连接到服务器或与服务器的连接已关闭.

Not connected to the server or the connection to the server has been closed.

我不知道如何解决它，它开始激怒了我，有人知道如何解决它?

I don't know how to solve it and it started to irritate me, anyone know how to fix it?

更新1

我一直在搜索，似乎是pgadmin4的问题(似乎是因为它不是100％开发的)，我一直在使用pgadmin3，并且没有出现该错误.

I have been searching and it seems the pgadmin4 the problem (it seems because it's not 100% developed yet), i have been using pgadmin3 and that error doesn't show up.

推荐答案

发生这种情况的原因是查询中的语法错误.检查语法，然后重试，也许就足够了

The reason this happened for me was a syntax error in the query. Check your syntax and try again, maybe this suffices
