Fix non-portable use of round().
round() is from C99. Use rint() instead. There are behavioraldifferences between round() and rint(), but they should not matter tothe Bloom filter optimal_k() function. We already assume POSIXbehavior for rint(), so there is no question of rint() not using"rounds towards nearest" as its rounding mode.Cleanup from commit51bc271.Per buildfarm member thrips.Author: Peter GeogheganDiscussion:https://postgr.es/m/CAH2-Wzn76eCGUonARy-wrVtMHsf+4cvbK_oJAWTLfORTU5ki0w@mail.gmail.com
