You can download an ARC/INFO interchange file here 
ftp://ftp.mrn.gouv.qc.ca/Public/Dgig/Produits/bdga1m/vectoriel/habit_p.zip

I used avcimport to produce de Arc/Info Coverage.



Sorry, I don't explain very well my ogrinfo outputs.

The first output was obtained by
$ ogrinfo /home/data/limites_qc/habit_p_ll/ lab
(where /home/data/limites_qc/habit_p_ll/ is a Arc/Info coverage)

The second was obtained by
$ ogrinfo PG:'dbname=prepa' habit_p_ll
(Where habit_p_ll is the database table obtained with ogr2ogr directly 
from the coverage describe above)

When I query my batabase with psql, I get exactly the same coordinate 
that orginfo.


Hope this help,
