Please do.
I would like to start testing the B-Tree code more exhaustively by
adding a test suite to amcheck. This test suite would indirectly test
external sorting, B-Tree page deletion, edge-cases with very large
IndexTuples, etc.
Ideas for good areas of the B-Tree code to add tests for are welcome.
