Usage

• pgping works by reading your PGCONN environment variable and attempting to connect to it.
• If it's able to establish a connection with the provided Postgres server and credentials, it exits with a 0 status.
• If it cannot, it prints the error to stdout and exits with a non-zero status.

PGCONN=postgres://postgres@localhost:5432/postgres?sslmode=disable pgping
