#### 2. Postgres Installation & Setup
Khoj uses the `pgvector` package to store embeddings of your index in a Postgres database. To use this, you need to have Postgres installed.
#### 2. Run
```mdx-code-block
<Tabs groupId="operating-systems">
<TabItem value="macos" label="MacOS">
Install [Postgres.app](https://postgresapp.com/). This comes pre-installed with `pgvector` and relevant dependencies.
</TabItem>
<TabItem value="win" label="Windows">
1. Use the [recommended installer](https://www.postgresql.org/download/windows/).
2. Follow instructions to [Install PgVector](https://github.com/pgvector/pgvector#windows) in case you need to manually install it. Windows support is experimental for pgvector currently, so we recommend using Docker. Refer to Windows Installation Notes below if there are errors.

##### Create the Khoj database
Make sure to update your environment variables to match your Postgres configuration if you're using a different name. The default values should work for most people. When prompted for a password, you can use the default password `postgres`, or configure it to your preference. Make sure to set the environment variable `POSTGRES_PASSWORD` to the same value as the password you set here.

#### Windows Installation Notes
1. Command `khoj` Not Recognized
- Try reactivating the virtual environment and rerunning the `khoj` command.
- If it still doesn't work repeat the installation process.
2. Python Package Missing *Usually says import xxx not recognized*
- Use `pip install xxx` and try running the `khoj` command.
3. Command `createdb` Not Recognized
- make sure path to postgres binaries is included in environment variables. It usually looks something like
```
C:\Program Files\PostgreSQL\16\bin
```
4. Connection Refused on port xxxx
- Locate the `pg_hba.conf` file in the location where postgres was installed.
- Edit the file to have **trust** as the method for user postgres, local, and host connections.
- Below is an example:
```
host all postgres 127.0.0.1/32 trust
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
```
4. Errors with installing pgvector
- Reinstall Visual Studio 2022 Build Tools with:
1. desktop development with c++ selected in workloads
2. MSVC (C++ Build Tools), Windows 10/11 SDK, and C++/CLI support for build tools selected in individual components.
- Open the x64 Native Tools Command Prompt as an Administrator
- Follow the pgvector windows installation [instructions](https://github.com/pgvector/pgvector?tab=readme-ov-file#windows) in this command prompt.
### Using Docker
Make sure you install the latest version of [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/).
