I don't think so ignoring NULL in RAISE statement is good idea (it is not
safe). We can replace NULL by some string (like "NULL") by default. I am
thinking about other possibilities.
1. some RAISE statement flag - but there was strong disagreement when I did
it last time
2. some plpgsql GUC variables like plpgsq.raise_ignore_null
3. accept a function from this patch
Now, I am thinking so @3 is good option. It can be really useful as last
rescue for other PL without possibility to raise rich PostgreSQL exception
- currently PLPythonu, partially PLPerl (where are more issues), probably
