How to use SQL Database Chain (error EAI_AGAIN)

[mgiammarco]

Hello,
I am trying to use the sql database chain with postgres database (on cloud).
I see documentation is not completed. By trial and error I think I have got right url (in server log I see no more ECONNREFUSED), but now I get "getaddrinfo EAI_AGAIN". I checked inside docker container and dns is resolved.
What else can I do?
Please note I had to escape the password because it contains @ sign.
Thanks,
Mario

It seems to me I have the same problem with mcp postgres tool because I get MCP error -32603:
