I think this must mean that you changed the schema of table tbl_payment
during this session, and then re-ran the function. plpgsql isn't as good
as it could be about dealing with intra-session changes of composite
types. The reference to "parameter 70" seems a bit odd though, it doesn't
seem like you have anywhere near 70 variables in that function ...

In recent versions, the opening quote of the function's body string counts
as line 1. If your attachment came through without extra wrapping, I'm
counting this as line 195:
pay_test.comment=payment.comment;
(thinks about it for a bit) Actually it seems more likely that a change
in the rowtype of "payment" caused this, ie some change in the output
column set of that "final_query" query. Difficult to guess more than
that without more context.
