Here are some instructions for setting up PostgreSQL for use with esmBot.
### 1. Install PostgreSQL.
=== "Debian/Ubuntu"
```sh
sudo apt-get install postgresql postgresql-client
```
=== "Fedora/RHEL"
```sh
sudo dnf install postgresql postgresql-server
```
=== "Alpine"
```sh
doas apk add postgresql
```
=== "Arch/Manjaro"
```sh
sudo pacman -S postgresql
```

### 2. (Optional) Tune PostgreSQL.
[PGTune](https://pgtune.leopard.in.ua/) is a useful tool for generating configuration files for your PostgreSQL database. It is highly recommended that you generate a config using this tool as it can increase stability and performance.

### 3. Create the bot user and database.
When you install PostgreSQL, it'll create a new user on your system that acts as the "superuser" of the database. You'll need to run Postgres commands as this user; however, you can run a command as that user without switching to it by using `sudo`.
First, you'll need to create a user that the bot can interact with as well as the database itself:
```sh
sudo su - postgres -c "createuser esmbot"
sudo su - postgres -c "createdb esmbot"
```
Then, launch the PostgreSQL shell for the next few commands:
```sh
sudo -u postgres psql
```
If you want to give the user a password, you can do so like this:
```sql
ALTER USER esmbot WITH PASSWORD 'new_password';
```
Once you're inside the shell, you'll need to make sure the bot owns the database and has permissions:
```sql
ALTER DATABASE esmbot OWNER TO esmbot;
```
You're done!

### Troubleshooting
If you get an error like `error: permission denied for table counts` when attempting to run the bot, try running these commands in the PostgreSQL shell:
