Sounds like a plan. In (2), it's even better to detoast the values

look at a small portion of the elements.
Hm, how can I do that? Toast is still a bit black magic to me... Do you
mean I should stick to having Datums in TextFreq?
Store both the Datum and the text *. If the latter is NULL, then grab
the datum, detoast and store the result in the text *. Next time you
need to look at it, it's already detoasted.
Yeah, I got that idea, but then I thought the chances of touching the
same element during binary search twice were very small. Especially now
when the detoasting occurs only when we hit a text Datum that has the
same length as the sought lexeme.
Still, I can do it if people feel like it.
