Hello.
I found a bug in the behaviour of plpgsql error handling system
while trying to handle foreign key violation exception.
When this error occured, control doesn't jump to exception handling block.
It moves to the next statement instead. When control leaves the
function exception is occured. So it's impossible to handle this kind of
exception.
Furthermore, the FOUND local variable is set to true after insert
statement which raises foreign key violation and
GET DIAGNOSTICS var = ROW_COUNT set var to 1.
Attached file contains sample that shows this bug.
Execute fk_violation_bug, fk_violation_bug2 and fk_violation_bug3
plpgsql functions to see this error.
