// Package pgxpool is a concurrency-safe connection pool for pgx.
|
|
/*
|
|
pgxpool implements a nearly identical interface to pgx connections.
|
|
|
|
Creating a Pool
|
|
|
|
The primary way of creating a pool is with `pgxpool.New`.
|
|
|
|
pool, err := pgxpool.New(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.NewConfig(context.Background(), config)
|
|
|
|
A pool returns without waiting for any connections to be established. Acquire a connection immediately after creating
|
|
the pool to check if a connection can successfully be established.
