Hi list!
I need to use PostGIS for some vector layers joined to other tables in =
my database...
I'm using also several shapefile layers.
Everything works fine except for these two functions when I try to query =
the PostGIS vector layers:=20
drawQuery()
queryByShape()

I have built OID and GIST indexes on my tables.


Things improves if I use drawQuery() on a single layer (active layer),
but queryByShape() always fails.

I have found some messagges about these problems in the mapserver and =
postgis mailing lists,
but I can't find a solution or a workaround...

Could any of you help me?


I'm using:
Mapserver  4.0
postgis    0.8.1
postgresql 7.3.3


PS: sorry for my poor English ;)
