Christian,

You are correct without any pqsurf.conf entries, pqsurf exits with a
signal 1.  So add the following entry to pqsurf.conf

IDS|DDPLUS  ^metar (....) ([0-3][0-9])([0-2][0-9])
    FILE    data/surface/metar/(\2:yy)(\2:mm)\2\3.wmo

Remember white spaces outside of the pattern part are tabs.

You can check pqsurf.conf by:

% ldmadmin  pqactcheck -p etc/pqsurf.conf

from ldm home dir.

I'm starting to believe your problem is with the DBFILE pqsurf.conf entry.
