## What it is
A large collection of Chinese-language technical articles, course materials, and video links about PostgreSQL, Greenplum, PolarDB, MySQL, and related database technologies, maintained by a prominent Alibaba database expert. It serves as a long-running knowledge base covering DBA practices, database internals, migration from Oracle, and modern topics like vector search and AI-assisted learning.

## Use cases
- learn postgresql administration and tuning
- migrate from oracle to postgresql
- study database internals and source code
- find postgresql best practices and development standards
- learn greenplum and analytics databases
- understand vector search with pgvector and milvus
- prepare for database architect interviews

## When to choose
- you want deep, practical PostgreSQL/DBA knowledge in Chinese
- you need structured course material for database training
- you are migrating from Oracle or MySQL to PostgreSQL
- you want to study source code of databases like DuckDB, Milvus, or pgvector

## When to avoid
- you need runnable software or a tool rather than articles
- you only read English and cannot work with Chinese-language content
- you need official vendor documentation instead of community experience

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, database
- domain: databases, tutorials, developer-tools
- platform: windows, cross-platform
- tags: postgresql, greenplum, mysql, oracle-migration, dba, chinese-language, blog-articles, database-training, vector-database, duckdb, polaris, polar-db, linux, macos
