Trigger aborted on error - Mailing list pgsql-hackers

Hi.
I've such problem :
I table with primary key and in trigger try to insert into this table data
wich violate constrain (not uniq). When ectually executing SPI_execp I got
a message "ERROR: cannot insert a duplicate key into a unique index" and
trigger executing is aborted. What should I do in order to get this error
as a result from SPI_execp and continue trigger execution?

Thanks in advance,
