pglogrepl_demo output does not look like the provided example output

[SylvainGarrigues]

pglogrepl_demo does not display in clear the inserted or updated values, for instance it displays:

2022/02/28 10:49:13 XLogData => WALStart 0/1740EC0 ServerWALEnd 0/1740EC0 ServerTime: 2022-02-28 10:49:13.171574 +0100 CET WALData Ct?t?|??}4

while the documentation says it should look like:

2019/08/22 20:04:59 XLogData => WALStart 3/A6693E68 ServerWALEnd 3/A6693E68 ServerTime: 1999-12-31 18:00:00 -0600 CST WALData table public.t: INSERT: id[integer]:1 name[text]:'foo'
