There are several reasons why large companies may choose to use PostgreSQL instead of MySQL: Advanced functionality: PostgreSQL offers more advanced features such as support for stored procedures, user-defined functions, and complex SQL queries.PostgreSQL is an object-relational database management system that offers more features than MySQL. It gives you more flexibility in data types, scalability, concurrency, and data integrity.Ispirer Toolkit automatically migrates the entire database schema (tables, views, stored procedures, functions, triggers, etc.) and transfers data from MySQL to PostgreSQL. A free demo of Ispirer Toolkit is available. pg_chameleon is a python procedure which replicates MySQL into PostgreSQL.

Why migrate from SQL Server to PostgreSQL : On the bright side, PostgreSQL provides several language options, all of which are more graceful than T-SQL. RDBMS all provide built-in functions. However, like procedural extensions to SQL, they are not portable. Fortunately, there is some overlap, and the simple syntax makes migration relatively easy.

Is it hard to migrate from MySQL to PostgreSQL

Migrating a MySQL database to PostgreSQL can be a challenging task, especially if you have a large and complex data set. However, with the right tools and steps, you can achieve a smooth and successful transition.

Is Postgres faster than MySQL : MySQL is generally known to be faster with read-only commands at the cost of concurrency, while PostgreSQL works better with read-write operations, massive datasets, and complicated queries.

PostgreSQL is reliable

PostgreSQL uses a Write-Ahead Log to protect against system crashes, so that if a transaction has committed that hasn't yet been written to the database, the Write-Ahead Log is replayed, and the transaction is then committed.

PostgreSQL comes with many features aimed to help developers build applications, administrators to protect data integrity and build fault-tolerant environments, and help you manage your data no matter how big or small the dataset.

Should I use Postgres or MySQL

MySQL is generally known to be faster with read-only commands at the cost of concurrency, while PostgreSQL works better with read-write operations, massive datasets, and complicated queries.You can have freedom from the relational model involving strict relationships like Foreign Key, relationships to other tables using Joins, Object-relational mapping, etc. Instead, Document-based NoSQL databases like MongoDB, CouchDB, etc., support encapsulation and can achieve a similar nature of the RDBMS facility.Steps

1. Install. postgres server. mysql client. pgloader CLI.
2. Create target database.
3. Perform the database migration: execute pgloader with the appropriate configuration parameters.
4. Post database migration. move all tables, indexes, and sequences to schema PUBLIC. ANALYZE the database.

Performance. For most workloads, the performance between Postgres and MySQL is comparable with at most 30% variations. On the other hand, regardless of which database you choose, if your query misses an index, it could be 10x ~ 1000x degradation.

Do people still use MySQL : MySQL is probably still the world's most popular open source database by install base.

What is the downside of Postgres : Disadvantages of PostgreSQL

• Postgres is not owned by one organization.
• Changes made for speed improvement requires more work than MySQL as PostgreSQL focuses on compatibility.
• Many open source apps support MySQL, but may not support PostgreSQL.
• On performance metrics, it is slower than MySQL.

Is MySQL more popular than Postgres

MySQL is probably still the world's most popular open source database by install base. While Postgres positions itself as the world's most advanced open source relational database.

Here's the conditions under which I think Postgres isn't a good choice for a data warehouse.

1. If you're unable to get a fast SSD for disk, then don't use Postgres.
2. If you really need real-time analytics or near real-time analytics don't use PG .

MySQL is preferred for managing read-only commands. It is not preferred when concurrency is required. PostgreSQL is preferred for managing read-write operations, large datasets, and complex queries. But it's not preferred for read-only operations.

Should I still use MySQL : MySQL is a good choice for simplicity, while PostgreSQL is ideal if you require advanced features, data integrity, and scalability. Both databases are widely used, so your choice should align with the demands of your projects.
