I am trying to migrate a DB to railway. I used to use SQLite with EFCore (I am in a C# .NET environment) , but after reading other threads I have heard it is discouraged so I am trying to transition from SQLite to postgres. I have an empty postgres DB running in my project and I took the URL and tried to run dotnet ef database update but I keep getting this error:
System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.27 Replies

the URL might not be in the format that the client wants, can you show me the URL format that is expected?

postgresql://myusername:mypassword@localhost:5432/mydatabase
maybe this?

I guess that is different from the private url

that would be the format the databases do come with, but what does your client expect the format to be?

i am unsure of what you mean

ok I uised A NpgsqlConnectionStringBuilder to fix the formatting issue, but now I have something which I am unsure of how to about

off the top of my head I'm not aware of any solutions to copy data from sqlite to postgres

I'm sure that's something someone has done before so do some research on the topic

While trying to read my data from a deployment on railway, I am getting the error: System.ArgumentNullException: Value cannot be null.
from the line:
Environment.GetEnvironmentVariable("DATABASE_PRIVATE_URL");which made me realize the variables on the postgres db cannot be seen from the other service (the actual bot) is there a way I am supposed to go about this?

yep! you want to be using reference variables, the docs for that are here along with an example -

hmm, so if my postgres db was called Postges
I would use Postges.DATABASEPRIVATEURL

almost, you do need the surrounding characters - ${{Postges.DATABASE_PRIVATE_UR}}

Oh I see, that part is in railway
