Function NewEngine

internal/query/postgres.go:51–56

NewEngine picks the appropriate engine for the given database. isPostgres selects between PostgreSQLQueryDialect (true) and SQLiteQueryDialect (false). This is the preferred entry point for callers that have a Store with an unknown backend — pass store.IsPostgres() as the flag. The return type is t

(db *sql.DB, isPostgres bool)

// The return type is the Engine interface so the SQLite-only TextEngine
// is hidden when isPostgres is true.
func NewEngine(db *sql.DB, isPostgres bool) Engine {
	if isPostgres {
		return NewPostgreSQLEngine(db)
	}
	return NewSQLiteEngine(db)
