CI is complaining about more than one definition of
<table id="extvacuumstatistics-pg-stats-vacuum-indexes-columns">
Looks like you mistakenly added this table the second time in
the 0007 patch instead of adding new columns to the already
existing table added in the 0005.

I reviewed the 0009 patch. If you add a new external function in
visibilitymap.c, i.e., visibilitymap_clear_rel, you should also
add it in the INTERFACE ROUTINES list in the beginning of the file.

I'd also suggest that the variation of the visibilitymap_clear
function taking a Relation should be the main one (and be called
visibilitymap_clear), and the variant taking a RelFileLocator
should be the additional one for those who don't have a Relation
(and be called visibilitymap_clear_no_stats or something). I am
not insisting, though.

Otherwise, the 0009 looks good to me. Except that I didn't look
at the documentation part closely. I'd leave it to the native
English speakers.
