Time for yet another “first patch” idea post ;-) This time it’s about BRIN indexes. Postgres has a contrib module called amcheck, meant to check logical consistency of objects (tables and indexes). At the moment the module supports heap relations (i.e. tables) and B-Tree indexes (by far the most commonly used index type). There is a patch adding support for GiST and GIN indexes, and the idea is to also allow checking BRIN indexes.
