Hi Tom,

Thanks for fixing these!
Unfortunately there's more - we'll currently do bad things if
transaction commit fails. At the very least the (sub-)transaction begin
commands need to be moved out of the exception block as they can
fail... :(. E.g. because this is the 2^32-1 subxact or similar...
I actually also want to strip the CATCH block of most of it's contents -
there's really no need anymore for most of what it does.
Greetings,
Andres Freund
