Right because that's select * from "Faxeingang" where "Filename" =
ddf.tif; (ie, a reference to a tif column of a table named ddf)

This is probably the same as the above (run just the echo part in your

This is select * from "Faxeingang" where "Filename" = "ddf.tif"
(ie, a reference to a column named ddf.tif in Faxeingang.

echo "select * from \"Faxeingang\" where \"Filename\"='ddf.tif';"
