# Description
|
|
|
|
This is a sample chat program implemented using PostgreSQL's listen/notify
|
|
functionality with pgx.
|
|
|
|
Start multiple instances of this program connected to the same database to chat
|
|
between them.
|
|
|
|
## Connection configuration
|
|
|
|
The database connection is configured via enviroment variables.
|
|
|
|
* CHAT_DB_HOST - defaults to localhost
|
|
* CHAT_DB_USER - defaults to current OS user
|
|
* CHAT_DB_PASSWORD - defaults to empty string
|
|
* CHAT_DB_DATABASE - defaults to postgres
|
|
|
|
You can either export them then run chat:
|
|
|
|
export CHAT_DB_HOST=/private/tmp
|
|
./chat
|
|
|
|
Or you can prefix the chat execution with the environment variables:
|
|
|
|
CHAT_DB_HOST=/private/tmp ./chat
|
