Tom Lane 960382e3e9 Doc: remove bogus claim that tsvectors can have up to 2^64 entries.
This is nonsense on its face, since the textsearch parsing logic
generally uses int32 to count words (see, eg, struct ParsedText).
Not to mention that we don't support input strings larger than
1GB.

The actual limitation of interest is documented nearby: a tsvector
can't be larger than 1MB, thanks to 20-bit offset fields within it
(see WordEntry.pos).  That constrains us to well under 256K lexemes
per tsvector, depending on how many positions are stored per lexeme.

It seems sufficient therefore to just remove the bit about number
of lexemes.
