Comment (by pcreso):

 When opening a PostGIS table, the features intially plot fine. If I then
 choose continuous colour (symbology) & select the field to use to define
 the colours, the max value displayed in the LHS legend for the layer bears
 no resemblance to the actual values of the selected column, eg: 111.0000
 is shown, but the dataset has values well into the thousands. Similarly,
 the min value shown in the legend is 0.00000, but the attribute table,
 sorted on the column, shows a minimum of 2.1

 The values shown, and the assigned colours are in fact from another column
 than the selected one, the prvious numeric column in the table.

 The correct values are shown in the attribute table, and if classification
 ranges are used instead of continuous colour, the correct numbers for the
 selected column are shown in the legend.
