You can't use transactions inside a function. The reason is that when
a function executes you are already inside a transaction (every SQL
statement is a transaction if there is no explicit BEGIN) and PG
doesn't support nested transactions.
See the FAQ for more info; I'm pretty sure this issue is in there (if
not, it should be).
