Tom Lane 973a210cce Tweak mdnblocks() to avoid doing lseek() on segments that it has ...

previously determined not to be the last segment of a relation.
This reduces the expected cost to one seek, rather than one seek per
segment.  We can get away with this because truncation of a relation
will cause a relcache flush and so the md.c file descriptor will be
closed; when it is re-opened we will re-determine the last segment.
