Thanks for the patch.

As a whole it contains all needed for ripping off the min_safe_lsn.
Some items in the TAP test gets coarse but none of them lose
significance. Compiles almost cleanly and passes all tests including
TAP test.

The variable last_removed_seg in slotfuncs.c:285 is left alone but no
longer used after applying this patch. It should be removed as well.

Other than that the patch looks good to me.

regards.
