Add a full PostgresSQL syntax database 'AnalyticDB' as vector store. (#3135) Hi there！ I'm excited to open this PR to add support for using a fully Postgres syntax compatible database 'AnalyticDB' as a vector.

It works better when data comes to large scale. The PR includes: - [x] A new memory: AnalyticDBVector - [x] A suite of integration tests verifies the AnalyticDB integration I have read your [contributing guidelines](https://github.com/hwchase17/langchain/blob/72b7d76d79b0e187426787616d96257b64292119/.github/CONTRIBUTING.md).
