Bug reference:      15600
Logged by:          Christoph Gößmann
Email address:      (redacted)
PostgreSQL version: 11.0
Operating system:   x86_64-pc-linux-gnu, compiled by gcc (GCC) 6.3.0
Description:        

Dear PostgreSQL team,

Today I encountered what I suspect is a bug of the ts_stat function where
nentry maxes out at 255, independent of more occurrences of e.g. the word
'hello'. On
https://www.postgresql.org/docs/11/release-11-1.html#id-1.11.6.5.5 I could
not find any changes that are connected to ts_stat.

Unexpected behaviour:
netry for 'hello' results in 255 despite 'hello' occurs 539 times in the
attached test.

The commands and output are as attached, the schema is attached last.

Many thanks,
Christoph
