 the CreateCursor function uses a fixed string + the current date and time
 for a unique cursor name.
 I have found many cases where 2 or more cursor are created in the same
 second, so the provider crashes with the "Cursor already exist" PostGIS
 message.

 Adding a random number at the end of the unique cursor name calculation
 should resolve this issue.
