In the https://www.postgresql.org/docs/12/adminpack.html，there is a function
which name is pg_logdir_ls() ，but there is no this function name from psql
query（the following query），why？

(0 rows) ---->>>there is no pg_logdir* function！！！
The commentary at the end of the TOC describes how to use the stuff described in the “Additional Supplied Modules” section.
In short, you haven’t installed the function from adminpack but core provide its own version.
