Hi!
select pg_read_file(pg_current_logfile())
retrieves today log file.
Log files are in log directory:
/var/lib/postgresql/12/main/log# ls
...
postgresql-2020-06-08_000000.log postgresql-2020-06-18_000000.log postgresql-2020-06-28_000000.log
postgresql-2020-06-09_000000.log postgresql-2020-06-19_000000.log

Using Postgres 12 in Debian.
