Thanks - that worked like a charm and is exactly what I was looking
for, of cause I can afford that, it's shutdown after the init anyway -
so after running pg_resetwal this was left:

root@53e0d45ce5d7:/var/lib/postgresql/data/pg_wal# ls -lh
total 17M
-rw------- 1 postgres postgres  16M Mär 11 17:23 000000010000000000000012
drwx------ 2 postgres postgres 4,0K Mär 11 17:13 archive_status

Nice one :) thanks.

kind regards
