Re: BRIN Scan: Optimize memory allocation in function 'bringetbitmap'

I forgot disable-c-assert last test.  
The following show the test result when disable-c-assert.
After optimize code (warm run)
postgres=# select count(*) from lineitem where l_orderkey=1;count
-------    6
(1 row)

Time: 327.143 ms
Before optimizing code (warm run)
postgres=# select count(*) from lineitem where l_orderkey=1;count
-------    6
(1 row)

Time: 404.323 ms

Here is the patch. patch_optimize_mem.patch_optimize_mem
<http://postgresql.nabble.com/file/n5867980/patch_optimize_mem.patch_optimize_mem>
