PostgreSQL
About PostgreSQL
PostgreSQL is an open-source relational database management system (RDBMS), which helps businesses store, manage, and scale data workloads, from single machines to data warehouses with multiple concurrent users. Features include materialized views, stored procedures, indexing, multi-factor authentication, full-text search, and event triggers.
The ACID-compliant system lets developers define data types such as numeric, date/time, array, or geometry, build custom functions, and maintain data integrity using exclusion constraints, explicit locks, and primary or foreign keys. Database administrators can utilize SQL to perform multiple data operations such as INSERT, UPDATE, DELETE, and more. Using foreign data wrappers, IT professionals can access external databases or streams for querying.
PostgreSQL maintains a write-ahead log (WAL), which helps developers record file changes and restore databases during system crashes. Administrators can grant role-based objects and column to table level permissions. Developers can also improve query performance on tables by using acceleration partition pruning, automatically invalidate cached execution plans, write background checkpoints, and restrict bandwidth usage for backup processes.

In general, my experience with postgress is more than satisfactory, it is an engine that works very well, it is stable, it allows me to handle large databases with tables of more than a million data without any problem. It has some syntax different from common sql, but they give great functionality (like data parsing)
Pros
Excellent database manager, it has its own program (phAdmin) that gives you a very friendly graphical interface to carry out all kinds of tasks. Postgress is highly scalable and stable, which is why I prefer it over other options
Cons
As against, when the database that is handled is relatively small, when comparing response speeds with other engines, it has a small disadvantage, but its great advantage is noted by having a large database.

Overall, we have a very productive experience with PostgreSQL. Whenever we need a backend database for any of the apps we deploy, we use PostgreSQL. It never fails us.
Pros
I like how easy it is to set up and deploy a PostgreSQL database. It has a rich ecosystem of tools and a great open-source community behind it.
Cons
I don't have anything I dislike about PostgreSQL.
Reasons for Choosing PostgreSQL
For some tools we deployed, we naturally needed to scale up and handle more complex workloads. So we changed our backend database.Switched From
SQLiteReasons for Switching to PostgreSQL
Out of many open-source tools we deploy, PostgreSQL is the most widely supported DB backend among others. So we decided to use PostgreSQL whenever applicable.- Used Daily for 6-12 months

It can operate on platform specifications, including Linux, Windows, Unix.
Large storage capacity
Good scalability since it is able to adjust to the number of CPU and the amount of available memory optimally, supporting a greater number of simultaneous requests to the database correctly.
It supports the types of data, clauses, functions and commands of standard type SQL92 / SQL99 and extended own of PostgreSQL ..
Pros
its graphic environment and considerable savings in operating costs: PostgreSQL has been designed to have a maintenance and adjustment lower than the products of commercial suppliers, while retaining all the characteristics, stability and performance. Stability and reliability: There have been no drops in the database
Cons
That Compared to MySQL is slower in insertions and updates, since it has intersection headers that do not have MySQL Support online: There are official forums, but there is no mandatory help It consumes more resources than MySQL .

Postgres is there for you whenever you need to store and retrieve simple tabular data. Whether that's your app user's name, email, and settings, or the projects and project content that they've created. As long as you're not dealing with over 10k transactions per second, it's cheap to use and extremely easy to set up. Oh, and it's also not great but just okay for advanced searching such as full-text search.
Pros
- Postgres is just soooo reliable, it's hard to corrupt or lose data unless you go in and manually edit or delete the data.
- Battle-tested ACID transactions to make sure you only update the data when it makes sense to have saved me so much time.
- The SQL interface is easy to use once you've mastered SQL (which it isn't; it's the simplest of all the languages I've learned).
- Newer versions even has support for advanced use cases such as arrays and JSON objects.
- The best thing is that 90% of the backend software developers know Postgres (or MySQL which is pretty dang similar) so help is never too far away!
Cons
The only real reason to not use Postgres is that it is pretty hard to scale. If your software requires over 10k transactions per second, you're gonna have to put in some serious work make Postgres scale. This is where Postgres becomes a pain to optimize. Postgres provides poor support for identifying the queries that are running really slowly. e.g. you have to install a buggy plugin and then query a funky poorly documented table. Trying to do master-slave replication is also quite difficult as you often run into consistency issues and will have to modify app logic. In these cases, it's better to go with NoSQL obviously.
Reasons for Switching to PostgreSQL
I picked Postgres over MySQL is not as battle tested and was behind Postgres in terms of JSON object support. I picked Postgres over MongoDB because it's easier to set up, didn't have anyone else on the team that knew how to use it (whereas all 5 of my teammates have Postgres experience), and because Postgres can handle our traffic currently.- Industry: Computer Software

I have been using PostgreSQL for 6 years in most of the applications I write. It is my default choice for a relational database.
Pros
PostgreSQL is a database that every programmer is familiar with. I value its versatility and universality. It's easy to implement it production-wise with not much scale.
Cons
Great for simple applications, when it comes to scaling/replication problems begin.
