field overflow when saving style

The layer style table has a field "f_table_name" which is char_varying(256). The idea is clearly to but the table name in here if the style applies to a postgis table. Fine. If the table is something more complicated (like a join) QGIS puts the SQL in the that field. If the text of the sql is over 256 characters the save fails with a misleading message about permission problems.

Firstly I suggest that the message be changed to something along the lines of "QGIS failed to insert this style in public.layer_style table. Most often this is a permission problem. See QGIS log for more details."

I would suggest that either QGIS does not save the sql in the name field or that it checks and truncates it if necessary.

Hmmm... I just changed the field type to text and it works fine now -- so that is another approach.

it seems to me that in the "f_table_name" is always place the name of the layer you are styling (no SQL), regardless if that layers have joins or not.

Can you provide an example?
