Loading of existing db is not working.

When we use the following function: const trie = await Trie.load(new Store('db')) following error is coming caught ModuleError: Database is not open` at maybeError (... node_modules/abstract-level/abstract-level.js:806:27) at ClassicLevel.get (.../node_modules/abstract-level/abstract-level.js:282:9) at Store.get .../node_modules/@aiken-lang/merkle-patricia-forestry/dist/index.cjs:207:44) at _Trie.load .../node_modules/@aiken-lang/merkle-patricia-forestry/dist/index.cjs:377:30) at REPL13:1:52 { code: 'LEVEL_DATABASE_NOT_OPEN'

Also what is the best way to store the trie into say a postgres database. What do we need to store as data structure that can be reloaded ? Something like a JSON based structure would be ideal.
