-- 查询所有数据
SELECT * FROM users;

2. Features and usage of PostgreSQL

PostgreSQL is a highly A customizable relational database management system with the following characteristics:

1. Powerful functions: PostgreSQL supports many advanced functions, such as complex queries, transaction support, and stored procedures.
2. Scalability: PostgreSQL supports plug-in architecture and can be customized and expanded according to the needs of the enterprise.

4. Multi-version control: PostgreSQL supports multi-version concurrency control, so that read and write operations can be performed simultaneously.
5. Community support: PostgreSQL has an active developer community that provides rich documentation and technical support.

The following is an example of using PostgreSQL to create a table, insert data and query data:

-- 创建一个名为users的表
CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  name VARCHAR(50),
  age INT
);

-- 插入一条数据
INSERT INTO users (name, age) VALUES ('Tom', 25);

-- 查询所有数据
SELECT * FROM users;

3. Comparison and selection

Both MySQL and PostgreSQL are excellent Database management systems have some common characteristics, such as high performance, scalability and data security. However, it is important to choose a database solution that suits your business based on your specific needs and environment.

If you have high requirements for ease of use and high performance, and want to be able to quickly build and deploy a database system, then MySQL may be a good choice.

If you need more powerful functions and customization capabilities, such as complex queries, transaction support, and stored procedures, then PostgreSQL may be more suitable for your needs.

Conclusion: MySQL and PostgreSQL are both database solutions suitable for small and medium-sized enterprises. They have their own characteristics and advantages, and it is very important to choose according to the specific needs and environment of the enterprise.
