[SQL] Setting the transaction isolation level for a stored procedure

[Keith Wong]

Sorry, I forgot to put a subject title in my last email. So here it is again.

Hi ppl,

Just wondering if anyone knows if its possible to set the transaction 
isolation
level from inside a stored procedure in plpgsql. Or do I need to run the 
'set transaction
isolation level' command before I called the stored procedure? I'm not even 
sure that
would work, I assume plpgsql uses the current transaction isolation level?
Any help would be much appreciated :)

Cheers, Keith.
