# PostgreSQL database

The Elimity Insights server manages all of its persistent data in a PostgreSQL database. For SaaS customers we perform the setup and maintenance of PostgreSQL servers behind the scenes. These installation instructions are mainly useful for on-prem deployments. We strongly recommend using your cloud provider's DBaaS offering to set up a PostgreSQL database. More specifically, Elimity Insights servers officially support PostgreSQL 15.x and 17.x. The `btree_gist`, `pgcrypto` and `plv8` extensions must also be available. If using your cloud provider's DBaaS offering is not an option, then installing PostgreSQL manually on e.g. a Linux VM is also possible.

We heavily recommend creating a dedicated database and user for Elimity Insights. More specifically, we suggest the following steps:

1. Create a dedicated PostgreSQL user with no privileges and a strong authentication mechanism
2. Create a dedicated database and assign the new user as its owner

Please note that v3.44 is the last release that will support PostgreSQL 15.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.elimity.com/reference-manual/v3.44.2/installation/postgresql-database.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
