<pre class="k9mail">Chasing a regression bug upon importing shapefile to postgresql [1]<br />I've stumbled upon an unclear semantic of the "length" member of<br />QgsField class [2].<br /><br />The Ogr provider, upon loading shapefiles, uses the DBF field width<br />_minus_one_, for reasons that are unknown to me. Upon writing a layer<br />to PostgreSQL, the missing _one_ results in values being too large<br />for the field size.<br /><br />So the solution to this bug seems to be a clear definition of what<br />QgsField::length is supposed to be, beacuse either Ogr provider is<br />doing a mistake in reducing that field by 1 or PostgreSQL provider<br />is doing a mistake in NOT augmenting that field by 1.<br /><br />Does anyone have an idea about how should QgsField::length be<br />interpreted ?<br /><br /><br />[1] <a href="http://hub.qgis.org/issues/15188">http://hub.qgis.org/issues/15188</a><br />[2] <a
