# Postgres Flake Template
|
|
|
|
This is a template for constructing a working environment for local
|
|
[Postgres](https://www.postgresql.org/) (version 15.5) usage. [direnv](https://direnv.net/)
|
|
can be used to a launch a dev shell upon entering this directory (refer to
|
|
`.envrc`). Otherwise run via:
|
|
```bash
|
|
$ nix develop
|
|
```
|
|
|
|
## Quickstart
|
|
|
|
An empty Postgres cluster is initialized at `/db`. To start the database, run
|
|
the following:
|
|
```bash
|
|
$ pg_ctl -D db -l db/logfile -o --unix_socket_directories=@postgres start
|
|
```
|
|
In the above command, `@postgres` refers to an [abstract socket name](https://www.postgresql.org/docs/15/runtime-config-connection.html#GUC-UNIX-SOCKET-DIRECTORIES).
|
|
Rename to whatever is appropriate for your use case. To then connect to this
|
|
database instance, run:
|
|
```bash
|
|
$ psql -h @postgres
|
|
```
|
|
To later shut the database down, run:
|
|
```bash
|
|
$ pg_ctl -D db stop
|
|
```
