// Package pgxpool is a concurrency-safe connection pool for pgx.
/*
pgxpool implements a nearly identical interface to pgx connections.
Establishing a Connection
The primary way of establishing a connection is with `pgxpool.Connect`.
pool, err := pgxpool.Connect(context.Background(), os.Getenv("DATABASE_URL"))
The database connection string can be in URL or DSN format. PostgreSQL settings, pgx settings, and pool settings can be
specified here. In addition, a config struct can be created by `ParseConfig` and modified before establishing the
connection with `ConnectConfig`.
config, err := pgxpool.ParseConfig(os.Getenv("DATABASE_URL"))
if err != nil {
// ...
}
config.AfterConnect = func(ctx context.Context, conn *pgx.Conn) error {
// do something with every new connection
}
pool, err := pgxpool.ConnectConfig(context.Background(), config)
