Great. BTW, I notice to my chagrin that 'reindex table
some_table_with_an_indexed_text_column' doesn't benefit from this,
apparently because tuplesort_begin_index_btree is used, and it knows
nothing about sortsupport. I have a feeling there's a good reason for
that, but I don't remember what it is; do you?
