Types

type Source

type Source struct {
	// contains filtered or unexported fields
}

Source represents a PostgreSQL database source for schema extraction.

func NewSource

func NewSource(connStr string) (*Source, error)

NewSource creates a new PostgreSQL source from a connection string.

func NewSourceFromDB

func NewSourceFromDB(db *sql.DB) *Source

NewSourceFromDB creates a new PostgreSQL source from an existing database connection. This is useful when you want to reuse an existing database connection for schema extraction purposes.

func (*Source) Close

func (s *Source) Close() error

Close closes the database connection if it was created by NewSource. If the connection was provided externally (via NewSourceFromDB), this is a no-op.

func (*Source) ExtractSchema

func (s *Source) ExtractSchema(ctx context.Context) (schema dberd.Schema, err error)

ExtractSchema extracts the complete database schema including tables and their references.
