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 DATABASE_URL and standard PostgreSQL environment variables (PGHOST, PGUSER, etc.)
You can either export them then run chat:
export PGHOST=/private/tmp
./chat
Or you can prefix the chat execution with the environment variables:
PGHOST=/private/tmp ./chat
