High-volume transactions have reduced failures and improve customer service efficiency

The best feature is performance, because of which I decided on PostgreSQL. I have also enabled the PG vector plugin on top of PostgreSQL. I have the opportunity to use two different features and two different flavors in a single product, which is the best thing about PostgreSQL. Initially, we had some hiccups around the performance part, but later we did indexing in PostgreSQL and now it is working very well. Even when we are doing 100,000 transactions in a day, PostgreSQL is working excellently. The interface is another best feature. If I need to do any query, I simply install the plugin on my local, which is pgAdmin. Through pgAdmin, I am able to communicate with PostgreSQL and execute all my SQL queries. I am getting a better UI with PostgreSQL as the backend, which is also one of the best options. PG vector is also very strong from PostgreSQL where I have implemented RAG and on a daily basis, I inject thousands of pages of PDF. More than 100 PDFs are coming into my system and one PDF is around 1,000 pages. We are injecting them into PostgreSQL and converting them into dimensions and inserting them into PG vector. The level of transactions we are doing on a daily basis is substantial, and we are getting very good throughput and low latency from PostgreSQL. When we were doing more than 50,000 transactions in a minute with the previous database, we were getting a lot of latency issues with threads getting blocked and abruptly closed unwantedly. After doing extensive research, we decided to move to PostgreSQL. Now, we are doing around 100,000 transactions in PostgreSQL and we are getting good throughput with no latency.

Unified course data has streamlined our AI study assistant and still needs better large-scale search

There can be compute spikes when we scale up, which we noticed during our intake season while processing millions of records. Massive similarity searches on a lot of vectors can spike the database CPU and potentially slow down API requests, so we had to move to a higher plan in Supabase for handling this during our intake season. There is no native hybrid search yet, which can combine keyword search and vector search. Supabase supports both, but combining them requires writing a custom Postgres function, while dedicated tools on other platforms allow you to do that out of the box. On some level, we face indexing complexity with Supabase Vector because although vectors expedite searches, we need to use indexes such as HNSW or IVF Flat. Tuning these indexes in Postgres requires advanced knowledge, and we needed a dedicated Supabase expert or to hire someone capable of understanding these complex queries and set this up for us, making it not a plug-and-play solution for a massive scale project with tens of millions of vectors. Vectors are stored in Postgres, and we can perform a lot of similarity searches on millions of vectors, which can spike database CPU and potentially slow down the app, but apart from that, everything seems positive.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable features are the price, stability, it is scalable and is used by our clients in small business environments, and it is a simple product to use."

"It is a world class, performer, a scalable database that is free and open source."

"Scalable, stable, and easy to manage database system, with a straightforward installation."

"PostgreSQL is an amazing product, very stable, predictable and reliable with rich set of features."

"As PostgreSQL is free, this enables us to develop applications without having to think about budgets, and give us greater flexibility."

"I worked for years on Oracle, and I decided to move on PostgreSQL because I think it is a first class product."

"This is an open-source solution, operates at a high speed, and supports more than one SQL language."

"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."

Cons

"There are many places that it could be improved through the provision of more plug-ins and extensions, such as data distribution, load balancing, new data types, indexing and searching, etc."

"Authentication config could be made easier."

"PostgreSQL could be used for small to medium databases but not for a huge production database."

"The scalability is limited."

"JSON support although great, it still has some gotchas, querying and manipulating JSON will be one of the topics I'd like to see some improvement, still feels not natural to work with it."

"As PostgreSQL is an open-source product, you do have to do a bit more configuration and management yourself."

"By far the biggest limitations are in replication support."

"I had some issues when I integrated with the Jupyter Notebook."

Pricing and Cost Advice

"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."

"This solution can offer a cheaper choice for customers since it is open-source."

"The community version of Postgre is basically free."

"Affordable solution."

"It could be much cheaper. If you would like to build an application on Amazon today, PostgreSQL is the standard database with Redshift. If you want other databases, you can add them, but PostgreSQL is the basis of everything. It's a question of money, that's it."

"It is free. There is no license on it."

"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."

"There is an annual license."
