Hi, I have written a trigger in plperl (I could not use pgsql due to the nature of the trigger). I know CREATE CONSTRAINT TRIGGER is not intended for general use, but it is pretty important that this trigger be run on commit of the transaction, as it needs to use data in other tables that can only be considered final on commit. When I run the trigger then this error appears in the logs: postgres FATAL: BeginInternalSubTransaction: unexpected state END It is caused by the first call to the spi_exec_query($sql) function. Would I be correct in assuming that plperl language triggers are not capable of running from a CREATE CONSTRAINT TRIGGER command? When the trigger is set up as a normal per row trigger then it executes without any problems.
