More info:

As user posgres I cna start the server with:

/usr/lib/postgresql/12/bin/postgres -D /var/lib/postgresql/12/main -c
config_file=/etc/postgresql/12/main/postgresql.conf

Then I can connect to it. But sysctl does not start the instance.

I am also getting this error message:

/var/run/postgresql/12-main.pg_stat_tmp/global.tmp": No such file or
directory
2019-12-10 08:35:02.360 EST [786] LOG: could not open temporary
statistics file "/var/run/postgresql/12-main.pg_stat_tmp/global.tmp": No
such file or directory

But if I create that directory manually I cna start the server,

As a reminder, this instance was recently upgarded from V11 to V12, if
thta is significant.
