Tom pushed patches for all supported back branches that raises the token length
from 256 to 10240 [1]. If it is a v13 or earlier [2], it also requires to
change the limit of line length (from 8192 to 20480). In v16 this limit was
completely eliminated using StringInfo [3].

In summary, this improvement will be available in the next minor releases.
