Recommendations to others considering PostgreSQL:
There is no reason to not use PostgreSQL, it is amazingly mature coming from Ingres and Dr Stonebreaker. It's been around forever and is really solid. A dozen or so commercial vendors have MPP and datawarehouse forks of it that they use.
Postgresql JSON features are very helpful for front-end usage and the indexes make most queries blazing fast.
We have no dba and really don't need one. The DB runs itself.
You do need to run a few dba tasks weekly like vacuum, analyze and backup.
Check your explain plans and make sure you have adequate queries. Review collected by and hosted on G2.com.
What problems is PostgreSQL solving and how is that benefiting you?
We are using it for data warehousing, basic data for web sites, blog storage, backup data and research data. It is also our main analytic database and transactional store.
It has saved us a lot of development time and money. Spring Data JPA and hibernate work perfect with PGSQL. pgADMIN and all JDBC SQL tools work perfect with it. Review collected by and hosted on G2.com.
