History
Tom Lane b6a164e5cb Fix assorted oversights in range selectivity estimation. 
calc_rangesel() failed outright when comparing range variables to empty
constant ranges with < or >=, as a result of missing cases in a switch.
It also produced a bogus estimate for > comparison to an empty range.

On top of that, the >= and > cases were mislabeled throughout.  For
nonempty constant ranges, they managed to produce the right answers
anyway as a result of counterbalancing typos.

Also, default_range_selectivity() omitted cases for elem <@ range,
range &< range, and range &> range, so that rather dubious defaults
were applied for these operators.

In passing, rearrange the code in rangesel() so that the elem <@ range
case is handled in a less opaque fashion.
