PL/pgSQL Lineage

[mordovets-nico]

Hi there!
I’m currently working on extracting data lineage from PL/pgSQL stored procedures, and I noticed that sqllineage — which relies on sqlfluff — currently focuses only on declarative SQL.

That said, I’d like to understand your direction:

1. If there were a way to extract an AST from imperative SQL blocks (e.g., BEGIN ... END, including IF, LOOP, PERFORM, EXECUTE, etc.), would you consider adding support for lineage extraction from them?
2. Do you see sqllineage as being strictly focused on declarative SQL, with procedural constructs intentionally out of scope?
