无法连接到 azure PostresSQL 数据库 - 用户名应采用 <用户名@主机名> Format

Question content

I cannot connect to azure postgresql database in golang application

wrong information:

fatal: invalid username specified. please check the username and retry connection. the username should be in <username@hostname> format. (sqlstate 28000))

There is no @ in my username.

I use gorm as orm and connect like this

dburl := fmt.sprintf("postgres://%s:%s@%s:5432/%s", dbuser, dbpass, dbhost, dbname)
db, err := gorm.open(postgres.open(dburl), &gorm.config{})

My variables look like this

postgres_password="password!"
db_host="some-url-with-dashes.postgres.database.azure.com"
app_port="8080"
postgres_user="postgresuser"
db_name="file"

My code does see them and creates dburl correctly, like this:

postgres://postgresuser:[email&#160;protected]:5432/file

I have tried changing the username and password


Correct answer


You must configure the parameters db_user_namespace to on. Do not do this.

Golang and Python: Understanding the DifferencesGolang and Python: Understanding the DifferencesApr 18, 2025 am 12:21 AM

The main differences between Golang and Python are concurrency models, type systems, performance and execution speed. 1. Golang uses the CSP model, which is suitable for high concurrent tasks; Python relies on multi-threading and GIL, which is suitable for I/O-intensive tasks. 2. Golang is a static type, and Python is a dynamic type. 3. Golang compiled language execution speed is fast, and Python interpreted language development is fast.

Golang vs. C  : Assessing the Speed DifferenceGolang vs. C : Assessing the Speed DifferenceApr 18, 2025 am 12:20 AM

Golang is usually slower than C, but Golang has more advantages in concurrent programming and development efficiency: 1) Golang's garbage collection and concurrency model makes it perform well in high concurrency scenarios; 2) C obtains higher performance through manual memory management and hardware optimization, but has higher development complexity.

Golang: A Key Language for Cloud Computing and DevOpsGolang: A Key Language for Cloud Computing and DevOpsApr 18, 2025 am 12:18 AM

Golang is widely used in cloud computing and DevOps, and its advantages lie in simplicity, efficiency and concurrent programming capabilities. 1) In cloud computing, Golang efficiently handles concurrent requests through goroutine and channel mechanisms. 2) In DevOps, Golang's fast compilation and cross-platform features make it the first choice for automation tools.

Golang and C  : Understanding Execution EfficiencyGolang and C : Understanding Execution EfficiencyApr 18, 2025 am 12:16 AM

Golang and C each have their own advantages in performance efficiency. 1) Golang improves efficiency through goroutine and garbage collection, but may introduce pause time. 2) C realizes high performance through manual memory management and optimization, but developers need to deal with memory leaks and other issues. When choosing, you need to consider project requirements and team technology stack.

Golang vs. Python: Concurrency and MultithreadingGolang vs. Python: Concurrency and MultithreadingApr 17, 2025 am 12:20 AM

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.

Golang and C  : The Trade-offs in PerformanceGolang and C : The Trade-offs in PerformanceApr 17, 2025 am 12:18 AM

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.

Golang and Python each have their own advantages: Golang is suitable for high performance and concurrent programming, while Python is suitable for data science and web development. Golang is known for its concurrency model and efficient performance, while Python is known for its concise syntax and rich library ecosystem.
