Over the past decade, many developers and professionals have compared MySQL with PostgreSQL, most of whom consider the latter to be more superior in performance. The supporters of PostgreSQL argue that its standard support and acid are more than MySQL. MySQL is also popular because there are many Linux Web application installation packages with it, but since

Use local indexes to improve PostgreSQL Performance
You may not know that PostgreSQL supports partial indexing of table data? Its advantage is that it can accelerate the reading speed of the indexed data without additional overhead. the best way is to index the data that is read repeatedly based on the given WHERE clause. this is suitable for some specific analys
The amount of data will be huge in the future/you cannot predict the size of the data. We recommend that you change to PostgreSQL.
After a certain amount of data is stored in MySQL (generally, the performance of a single MySQL table is the best-, and the performance starts to decline when there are more data), the performance
