[SQL] INSERT [IGNORE] INTO TABLE

[Petr Jezek]

        If I try to insert some row which in the table already exist the
        postgre don't insert it and tell some error. Everything ok.
        I'll insert only if there is not the same (same key) record,
        else don't insert and don't tell me errors about it.
        In MySQL is a switch [IGNORE]. 

                                Thanx for help
