# List Databases Available For Connecting
|
||
|
||
I tend to have a couple different versions of Postgres installed on my
|
||
development machine. Each server version tends to have a different set of
|
||
databases. As I switch between projects and Postgres versions, it can be hard
|
||
to remember the name of the database to which I want to connect when using
|
||
`psql`.
|
||
|
||
I usually connect to one of the defaults, which is either named `postgres` or
|
||
named after the machine user.
|
||
|
||
There is a better way. I can first ask `psql` to list all the available
|
||
databases.
|
||
|
||
```
|
||
❯ psql --list
|
||
Timing is on.
|
||
List of databases

||
Name | Owner | Encoding | Collate | Ctype | Access privileges
|
||
--------------------------------+------------+----------+-------------+-------------+---------------------------
|
||
jbranchaud | jbranchaud | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
|
||
postgres | jbranchaud | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
|
||
thirty_days_server_development | jbranchaud | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
|
||
thirty_days_server_test | jbranchaud | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
|
||
(4 rows)
|
||
```
|
||
|
||
Then I know before connecting which one I'm looking for or if it must be in the
|
||
data directory of another Postgres server version.
