What is PostgreSQL?
PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions.
What is CouchDB?
What is HBase?
Apache HBase is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al. Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop.

PostgreSQL is our main datastore, and we make judicious use of its fantastic features: JSON columns, recursive CTEs, streaming binary replication, triggers, and constraints, among others.
SmartLogic uses PostgreSQL
When we need to keep data in a safe place, we turn to PostgreSQL. Not only is the software rock-solid, but new versions add amazing features like JSON support that give us the best of both worlds: SQL and NoSQL.

General relational data for configuration and integration. Some reporting. Use as a better "mongo" for json document storage.
TribeMedia uses PostgreSQL
We use PostgreSQL for all transactional data storage where data must remain consistent at all times (not eventually consistent like document databases).
Cloudcraft uses PostgreSQL
PostgreSQL combines the best aspects of traditional SQL databases such as reliability, consistent performance, transactions, querying power, etc. with the flexibility of schemaless noSQL systems that are all the rage these days. Through the powerful JSON column types and indexes, you can now have your cake and eat it too! PostgreSQL may seem a bit arcane and old fashioned at first, but the developers have clearly shown that they understand databases and the storage trends better than almost anyone else. It definitely deserves to be part of everyone's toolbox; when you find yourself needing rock solid performance, operational simplicity and reliability, reach for PostgresQL.

aleccunningham uses PostgreSQL
I use PostgreSQL due to its frequency of updates compared to MySQL, and based on preference. Nginx + PostgreSQL + Gunicorn is the best stack for running a Django based API.
yevgnenll uses PostgreSQL
django 프로젝트는 orm을 사용하기 때문에 DB를 변경하는것에 대한 두려움이 없습니다. 하지만 굳이 postgreSQL 을 사용한 것은 json 형식으로 저장이 가능하다는 점 때문입니다. 이것을 어떻게 사용할지는 아직 모르겠는것이 사실입니다.
하지만 restful api를 구축할때 이 부분에 대해 심도있게 다룰 예정입니다.
ralic uses PostgreSQL
Installed PostgreSQL server. Maintain database administration and database migration.
ReviewTrackers uses PostgreSQL
PostgreSQL is responsible for nearly all data storage, validation and integrity. We leverage constraints, functions and custom extensions to ensure we have only one source of truth for our data access rules and that those rules live as close to the data as possible. Call us crazy, but ORMs only lead to ruin and despair.
tj uses PostgreSQL
Postgres is used as the primary data store for users, checks, alerts and so on, as well as some aggregated stats.

AngeloR uses PostgreSQL
We use postgresql for the merge between sql/nosql. A lot of our data is unstructured JSON, or JSON that is currently in flux due to some MVP/interation processes that are going on. PostgreSQL gives the capability to do this.
At the moment PostgreSQL on amazon is only at 9.5 which is one minor version down from support for document fragment updates which is something that we are waiting for. However, that may be some ways away.
Other than that, we are using PostgreSQL as our main SQL store as a replacement for all the MSSQL databases that we have. Not only does it have great support through RDS (small ops team), but it also has some great ways for us to migrate off RDS to managed EC2 instances down the line if we need to.
mfbx9da4 uses PostgreSQL
Used in great detail at Cloudfind. Profiled and improved bulk SQL upsert performance 200 fold.
emidln uses PostgreSQL
Relational data stores solve a lot of problems reasonably well. Postgres has some data types that are really handy such as spatial, json, and a plethora of useful dates and integers. It has good availability of indexing solutions, and is well-supported for both custom modifications as well as hosting options (I like Amazon's Postgres for RDS). I use HoneySQL for Clojure as a composable AST that translates reliably to SQL. I typically use JDBC on Clojure, usually via org.clojure/java.jdbc.
Emcee uses PostgreSQL

HomeActions uses PostgreSQL
RDBM and Document storage combined with good performance makes this a must-have for HomeActions.
jflynn33 uses PostgreSQL
Tried MongoDB - early euphoria - later dread. Tried MySQL - not bad at all. Found PostgreSQL - will never go back. So much support for this it should be your first choice. Simple local (free) installation, and one-click setup in Heroku - lots of options in terms of pricing/performance combinations.

Pinterest uses HBase
The final output is inserted into HBase to serve the experiment dashboard. We also load the output data to Redshift for ad-hoc analysis. For real-time experiment data processing, we use Storm to tail Kafka and process data in real-time and insert metrics into MySQL, so we could identify group allocation problems and send out real-time alerts and metrics.
