include a fractional part in the output for MILLISECOND and SECOND cases, rather than truncating the source value. This is what the float-timestamp code has always done, and it was clearly the code author's intent to do the same for integer timestamps, but he forgot about integer division in C. The other datatypes supported by EXTRACT() already do this correctly. Backpatch to 8.4, so that the default (integer) behavior of that branch will match the default (float) behavior of older branches. Arguably we should patch further back, but it's possible that applications are expecting the broken behavior in older branches. 8.4 is new enough that expectations shouldn't be too settled. Per report from Greg Stark.
