The post asks if Llama Index supports agents that can read data from and write data to SQL databases like PostgreSQL and SQLite. The comments suggest that there are tools available on Llama Hub that can be used for this purpose, and one community member mentions a specific tool called "llama-index-tools-database" that allows for database reads. However, another community member notes that the import for this tool is outdated, and the updated import does not seem to work. The comments indicate that the tool can be installed using pip install llama-index-tools-database, but there is no explicitly marked answer to the original question.
