the H. Varchar is better though as the table is smaller.<o:p></o:p></span></p>

<span style="background:white">I'm trying to style some flooding probability data. It's in PostGIS and I'm using QGIS master (same issue in 2.0 and 2.2 though). My polygon layer has a probability field with values H, M and L. If I select a categorised style
using the probability field I get the expected three values. And an extra one. And the data is drawn using the style of the extra category - in the screenshot the pink lines and not the blues as expected. If I delete the extra category from the classification
table then nothing is drawn on the canvas. I have checked the field and there are only three unique values in it without nulls or blanks. The table is properly indexed with a primary key and GIST spatial index.</span><br>
<br>
<span style="background:white">So, is it a QGIS style engine problem or a PostGIS data problem? I should add that the same data from PostGIS draws perfectly in ArcGIS 10.2.2 and is styled as expected. </span></span><o:p></o:p></p>
