Types

type ConnConfig 

type ConnConfig struct {
	Host     string
	Port     string
	Username string
	Password string
}

ConnConfig holds the connection parameters shared by all PostgreSQL connectors.

func ParseConnConfig 

func ParseConnConfig(config map[string]string) (ConnConfig, string, error)

ParseConnConfig parses host, port, username, and password from the "location" URI and from standalone config keys. Standalone keys override URI components. The path component of the URI (i.e. the database name) is returned separately so callers can handle it as appropriate (use it, reject it, or ignore it).

func (ConnConfig) Args 

func (c ConnConfig) Args() []string

Args returns the common connection flags shared by all PostgreSQL client tools: -h host -p port -w, plus -U username when one is configured.

func (ConnConfig) Env 

func (c ConnConfig) Env() []string

Env returns the current process environment with PGPASSWORD injected when a password is configured.

func (ConnConfig) Ping 

func (c ConnConfig) Ping(ctx context.Context, psqlBin, connectDB string) error

Ping verifies connectivity by running SELECT 1 against the server. If connectDB is empty, "postgres" is used.
