[gnome-db] Issue with postgresql provider (3.0.2)

[Phil Longstaff <plongstaff rogers com>]

I have an issue with libgda, specifically the postgresql provider.

I basically create a GdaQuery with text "INSERT INTO <some-table> 
VALUES(<some values)".

When I call gda_query_execute( query, ..., &error ), the error is filled 
in with a GDA_QUERY_EXEC_ERROR with the text "INSERT 0 1".  This doesn't 
happen with sqlite or mysql.  The postgres provider specifically 
generates an event in compute_retval_from_pg_res() when the status is 
PGRES_COMMAND_OK.  gda_query_execute() then compares the events before 
and after, and because there is this new event, it is copied via 
g_set_error().

The same happens when my query is "DELETE FROM <some-table> WHERE 
<some-condition>", but the error string is "DELETE 0" (or maybe "DELETE 
n" when n rows are deleted).

Is this a bug in libgda, or is this expected behaviour?  Should I be 
testing the returned error to see if it begins with "INSERT" or "DELETE" 
and ignore it?  Should I clear the connection events, execute the query, 
then look at the events myself and ignore the returned error (the event 
has type GDA_EVENT_NOTICE or something like that)?
