I have found what causes it, in dal.py in PostgreSqlAdapter this method is
supposed to return last inserted id:
def lastrowid(self,table = None):
self.execute("select lastval()")
return int(self.cursor.fetchone()[0])
This here
http://stackoverflow.com/questions/17819001/postgres-not-returning-lastval-properly
says this the wrong way to ask for ID and that it should be returned this
way:
insert into table ([columns]) values ([values]) returning id
So it will return wrong ID everythime there is trigger that inserts
something else somewhere else.
I'm sending a bug report
