Thread: pgsql: Move EXPLAIN counter increment to heapam_scan_bitmap_next_block
Move EXPLAIN counter increment to heapam_scan_bitmap_next_block Increment the lossy and exact page counters for EXPLAIN of bitmap heap scans in heapam_scan_bitmap_next_block(). Note that other table AMs will need to do this as well Pushing the counters into heapam_scan_bitmap_next_block() is required to be able to use the read stream API for bitmap heap scans. The bitmap iterator must be advanced from inside the read stream callback, so TBMIterateResults cannot be used as a flow control mechanism in BitmapHeapNext().
