>Hi All,
now I have testet to set up the WFS with using a MySQL-Database instead of
PostgreSQL. With MySQL everything works fine but with PostgreSQL it doesn't.
A "ogrinfo" request on the commandline works perfect in both cases. With a
WMS its the same, only the WFS which doesn't work with PostgreSQL. Has
anybody an idea what can be the reason for that?
Best Regards
Christian
