utilities to work with the PostgreSQL database

With this crate it is easy to get a PostgreSQL configuration with the most common settings.

let pgdb = qm::pg::DB::new("example", &qm::pg::DbConfig::new()?).await?;

The Config is populated with environment variables. By default, all variables with the prefix PG_ are considered.

The prefix can be changed by using a builder pattern.

let example_config = qm::pg::DbConfig::builder().with_prefix("EXAMPLE_").build()?;

These variables are available and are set with the following defaults.

variable	struct field	default
PG_HOST	host	"127.0.0.1"
PG_PORT	port	5432
PG_MAX_CONNECTIONS	max_connections	32
PG_MIN_CONNECTIONS	min_connections	0
PG_ACQUIRE_TIMEOUT	acquire_timeout	30
PG_IDLE_TIMEOUT	idle_timeout	`10 * 60`
PG_MAX_LIFETIME	max_lifetime	`30 * 60`
PG_USERNAME	username
PG_PASSWORD	password
PG_DATABASE	database
PG_ROOT_USERNAME	root_username
PG_ROOT_PASSWORD	root_password
PG_ROOT_DATABASE	root_database
PG_SHARDED	sharded	false
	address	With credentials: `postgresql://{username}:{password}@{host}:{port}/`; With username: `postgresql://{username}@{host}:{port}/`; Without: `postgresql://{host}:{port}/`; If provided, `database` will be appended
	root_address	With credentials: `postgresql://{root_username}:{root_password}@{host}:{port}/`; With username: `postgresql://{root_username}@{host}:{port}/`; Without: `postgresql://{host}:{port}/`; If provided, `root_database` will be appended
