It should not work if you make a polygon selection.<br>
Tooltip and Click sends a square, so the envelope of the filter should
be the same as the filter<br>

It is actually forwarded to PostGIS:<br>
<br>
<tt> OGREnvelope sEnvelope;<br>
<br>
m_poFilterGeom->getEnvelope( &sEnvelope );<br>
osWHERE.Printf("WHERE %s && SetSRID('BOX3D(%.12f %.12f,
%.12f %.12f)'::box3d,%d) ",<br>
pszGeomColumn,<br>
sEnvelope.MinX, sEnvelope.MinY,<br>
sEnvelope.MaxX, sEnvelope.MaxY,<br>
nSRSId );<br>
</tt><br>
<br>
Not too good with PostGIS syntax, but since the m_poFilterGeom is the
filter used (a small square in this case) it reads:<br>
"Select from geometry_column where features are within the bbox of the
filer"<br>
<br>
Which should be quite ok, unless they have a similar idea of optimizing
this to a BBOX test, as OGR does.<br>
<br>
Anyway, I can confirm that Traians fix works with MapInfo TAB files,
but NOT with PostGIS :(<br>

I tried it with MapInfo TAB files, and it works fine.
Maciej, can you post an SQL dump of one of the PostGIS tables?
I have installed PostGIS on my machine for testing, but I have no data,
and no luck getting Fdo2Fdo working with FDO OGR.
