The post asks for good examples of using llamaindex with Postgres. The comments provide some helpful information:
A community member suggests checking out the Postgres example in the llamaindex documentation. Another community member asks if it's possible to create SQL queries, and a third community member provides a link to an example of using SQL indices with llamaindex. The final comment indicates that the combination of the two examples will work.
There is no explicitly marked answer, but the community members have provided some useful resources and information to help address the original question.
