have you tried to follow the Tom Lane suggestion to explicit cast the
first parameter in the call to round function ?
Anyway, to avoid writing queries and triggers to port existing
database to newer versions of Postgres you can define the following
very simple function:
-----------------------------------------------------------------
create function round (double precision, integer) returns double
precision as '
select cast(round(cast($1 as numeric),$2) as double precision);
' LANGUAGE SQL with(iscachable) ;
----------------------------------------------------------------
I hope this can help someone.
