Types

type CleanupFunc

type CleanupFunc func()

CleanupFunc deletes the schema and all database objects.

func NewPostgresSchema

func NewPostgresSchema(t *testing.T, sqlFiles []string, opts ...Option) (*pgx.Conn, CleanupFunc)

NewPostgresSchema opens a connection with search_path set to a randomly named, new schema and loads all sqlFiles.

func NewPostgresSchemaString

func NewPostgresSchemaString(t *testing.T, sql string, opts ...Option) (*pgx.Conn, CleanupFunc)

NewPostgresSchemaString opens a connection with search_path set to a randomly named, new schema and loads the sql string.

type GuardedStmtCache

type GuardedStmtCache struct {
	*stmtcache.LRU
	// contains filtered or unexported fields
}

GuardedStmtCache errors if any name in names is used to get a cached statement. Allows verifying that PrepareAllQueries works by creating prepared statements ahead of time. pgx accesses a map of prepared statements directly rather than calling Get.

func NewGuardedStmtCache

func NewGuardedStmtCache(conn *pgconn.PgConn, names ...string) *GuardedStmtCache

func (*GuardedStmtCache) Get

func (sc *GuardedStmtCache) Get(ctx context.Context, sql string) (*pgconn.StatementDescription, error)

type Option

type Option func(config *pgx.ConnConfig)

func WithGuardedStmtCache

func WithGuardedStmtCache(names ...string) Option

WithGuardedStmtCache is a functional option to initialize a the pgtest conn with a guarded cache that fails if pgx attempts to cache any SQL query in names. The names are typically SQL statements.
