I don't see any memory leak here.
In CVS tip, what is actually happening is that with the default setting
of temp_buffers = 1000, you can have up to 80MB worth of buffers for the
temporary table. The process expands to that size and then stops
expanding. If you set temp_buffers to 100 or so, it stops much sooner.
In 8.0.3 I don't see any "leak" at all --- the process size sits at
about 5MB for me.
It could be that 1000 is an overly large default setting for temp_buffers.
