I thought this sounded pretty cool: > It doesn't copy the data into it, it actually lets the SQLite engine use Excel tables as the data storage (I implemented something SQLite calls a virtual table - an adapter to let it work with custom data sources). This means you can run update/delete/insert statements directly on excel tables (from the linked reddit post, I haven't finished the blog post) I wonder if a similar sort of approach with FDW's could work with Postgres and Excel.
