Feature #4964

Description
Implement a function for raising error messages and notices from user functions. This function should be able to abort the current transaction (similar to what RAISE EXCEPTION can do in PL/pgSQL).

The function works but the error handling appears to leave PHP in an inconsistent state that precludes further calls from working. Example:
create function raise_strange(int) returns void language plphp as $$
pg_raise('notice', "$argsr0");
pg_raise('error', 'this is an error');
$$;
Invoking this function twice gives this output:
pl_regression=# select raise_strange(1); NOTICE: plphp: 1 ERROR: plphp: this is an error pl_regression=# select raise_strange(1); NOTICE: plphp: Undefined variable: _args_int NOTICE: plphp: Undefined variable: _argc_int NOTICE: plphp: ERROR: plphp: this is an error
The second call is clearly wrong.

- Status changed from In Progress to Closed
- Resolution set to fixed
Fixed in r22. Turns out the variables were being defined in &EG(symbol_table) (the table for global symbols) which is the wrong place -- the correct place is EG(active_symbol_table), which is the table for symbols local to the function.
