Types

type Client

type Client struct {
	Pgx    PgxIface
	Logger *logger.Logger

	// This is the stdlib connection that is used for transactions
	SQLDB *sql.DB
	// contains filtered or unexported fields
}

A wrapper around a pgxpool.Pool and sql.DB reference.

Each service should have a single instance of the Client to share a connection pool, schema (driven by the service namespace), and an embedded file system for migrations.

The 'search_path' is set to the schema on connection to the database.

If the database config 'runMigrations' is set to true, the client will run migrations on startup, once per namespace (as there should only be one embedded migrations FS per namespace).

Multiple pools, schemas, or migrations per service are not supported. Multiple databases per PostgreSQL instance or multiple PostgreSQL servers per platform instance are not supported.

func New

func New(ctx context.Context, config Config, logCfg logger.Config, o ...OptsFunc) (*Client, error)

func (*Client) Close

func (c *Client) Close()

func (Client) Exec

func (c Client) Exec(ctx context.Context, sql string, args []interface{}) error

Common function for all exec calls

func (*Client) MigrationDown

func (c *Client) MigrationDown(ctx context.Context, migrations *embed.FS) error

func (*Client) MigrationStatus

func (c *Client) MigrationStatus(ctx context.Context) ([]*goose.MigrationStatus, error)

func (*Client) MigrationsEnabled

func (c *Client) MigrationsEnabled() bool

func (Client) Query

func (c Client) Query(ctx context.Context, sql string, args []interface{}) (pgx.Rows, error)

Common function for all query calls

func (Client) QueryRow

func (c Client) QueryRow(ctx context.Context, sql string, args []interface{}) (pgx.Row, error)

Common function for all queryRow calls

func (*Client) RanMigrations

func (c *Client) RanMigrations() bool

func (*Client) RunMigrations

func (c *Client) RunMigrations(ctx context.Context, migrations *embed.FS) (int, error)

RunMigrations runs the migrations for the schema Schema will be created if it doesn't exist

func (*Client) Schema

func (c *Client) Schema() string

type Config

type Config struct {
	Host          string `yaml:"host" default:"localhost"`
	Port          int    `yaml:"port" default:"5432"`
	Database      string `yaml:"database" default:"opentdf"`
	User          string `yaml:"user" default:"postgres"`

	Schema        string `yaml:"schema" default:"opentdf"`

	VerifyConnection bool `yaml:"verifyConnection" default:"true"`
	MigrationsFS     *embed.FS
}

type OptsFunc

type OptsFunc func(c Config) Config

func WithMigrations

func WithService

func WithService(name string) OptsFunc

type PgxIface

type PgxIface interface {
	Acquire(ctx context.Context) (*pgxpool.Conn, error)
