Обсуждение: PLPGSQL/EXCEPTION HANDLING

In a function implemented in 7.4.8 I had the following error when I call
the function:

ERROR:  syntax error at or near "EXCEPTION"

Offending line is:
    EXCEPTION WHEN dup_val_on_index THEN NULL;

When this line is removed, all is well.

Any help appreciated...

that's because that construction was added in 8.0, you have to upgrade to use it

What part of the original  construction is  not supported?
Are any "exception when" statements supported?

Thanks

all the BEGIN .. EXCEPTION block:

[ <<label>> ]
[ DECLARE
    declarations ]
BEGIN
    statements
EXCEPTION
    WHEN condition [ OR condition ... ] THEN
        handler_statements
    [ WHEN condition [ OR condition ... ] THEN
          handler_statements
      ... ]
END;


all you can do until 7.4.x was:
