Tomas Vondra 04e72ed617 BitmapHeapScan: Push skip_fetch optimization into table AM ... Commit 7c70996ebf introduced an optimization to allow bitmap scans to operate like index-only scans by not fetching a block from the heap if none of the underlying data is needed and the block is marked all visible in the visibility map. With the introduction of table AMs, a FIXME was added to this code indicating that the skip_fetch logic should be pushed into the table AM-specific code, as not all table AMs may use a visibility map in the same way. This commit resolves this FIXME for the current block. The layering violation is still present in BitmapHeapScans's prefetching code, which uses the visibility map to decide whether or not to prefetch a block. However, this can be addressed independently.
