refactor!: Refactor PostgresVectorStore to depend on PGVectorstore
AsyncPostgresVectorStore and PostgresVectorStore are refactored to depend on the AsyncPGVectorStore and PGVectorStore respectively.
Hybrid search is now supported in PostgresVectorStore. Tests for hybrid search have been added.
BREAKING CHANGE:
The support for text filters in similiarity searches has been removed, and we support only dictionary filters now.
The dependency on langchain-core and pgvector is based on LangChain-Postgres's specifications.
