Hi strk,

Indeed you are right.
The trouble is that for some files there are too many of those errors
although the table is successfully loaded into the database.

Just in case you might provide me an opinion.
Do you think that shp2pgsql is too stringent regarding to the definition
of the MULTILINESTRING or something else, while viewers like ArcView
and JUMP are more tolerant and avoid annoying the user about those problems?

I have the impression that nothing is missed despite of that error message.

thank you very much :-)

The messages (althought written in non correct english) says
that some of the multilinestrings has just one vertex, being illegal
MultiLineStrings. The number shown is the shape number, and it seems
to be just some of the shapes to have this problem. You should have
no problems in feeding tm_26_set_02.sql to pgsql, you will just have
some NULL records in the resulting table.

Let me know if this is not the case.


message is sen
