I have the impression it's not quite working correctly. The attached program returns different results for different values of enable_bitmapscan (consistently). ( Btw, I had to make the max_locks_per_transaction higher for even not-so-large tables -- is that expected? For a 100M row table, max_locks_per_transaction=1024 was not enough; I set it to 2048. Might be worth some documentation, eventually. ) >From eyeballing the results it looks like the minmax result (i.e. the result >set with enable_bitmapscan = 1) yields only the last part because the only 'last' rows seem to be present (see the values in column i in table tmm in the attached program).
