Supabase is built on top of [Postgres](/docs/postgres/server/about), an extremely scalable Relational Database.

## Features

### Table View 

You don't have to be a database expert to start using Supabase. Our table view makes Postgres as easy to use as a spreadsheet.

### Additional features

- Supabase extends Postgres with realtime functionality using our [Realtime Server](/docs/realtime/server/about).
- Every project is a full Postgres database, with `postgres` level access.
- Managed backups - Supabase handles all your database backups.
- Data imports - import directly from a CSV or excel spreadsheet.

## Extensions


### Enable and disable extensions

To expand the functionality of your Postgres database, you can use extensions.
You can enable Postgres extensions with the click of a button within the Supabase dashboard.

### Full list of extensions

Supabase is pre-configured with over 50 extensions. You can also install your own SQL extensions directly into the database through our SQL editor.

## Tips

### Realtime 

Supabase provides a realtime engine on top of Postgres, so that you can listen to changes as they happen. 
Our realtime engine uses the built-in replication functionality of Postgres. 
You can manage the realtime system, simply by 
[updating](http://localhost:3006/docs/reference/postgres/publications) the `supabase_realtime` publication.

For example to enable realtime only for individual tables:

```sql
begin; 
  -- remove the realtime publication
  drop publication if exists supabase_realtime; 

  -- re-create the publication but don't enable it for any tables
  create publication supabase_realtime;  
commit;

-- add a table to the publication
alter publication supabase_realtime add table products;

-- add other tables to the publication
alter publication supabase_realtime add table posts;
```

By default only "new" values are sent, but if you want to receive the old record (previous values) whenever you `update` or `delete` a record, 
you can update the replica identity of your tables, setting it to `full`:

```sql
alter table_name your_table 
replica identity full;
```


### Resetting your project password

When you create a new project in Supabase we ask for a password. You can use this password to connect direcly to your Postgres database.

If you forget your password, you can reset it from the Dashboard SQL editor:

For example:

```sql
alter user postgres 
with password 'new_password';
```

Read more in [Database Configuration](/docs/reference/postgres/database-passwords).

### Changing the timezone of your server.

Your database is initialized with the UTC timezone. We recommend keeping it this way, as it is helpful for time calculations.
If, however, you want to update the timezone, you can do so using any of the [database timezones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).

For example:

```sql
alter database postgres set timezone to 'America/New_York';
```
