If you want to keep the same functions just do as follows
CREATE OR REPLACE FUNCTION nvl(TEXT,TEXT) RETURNS TEXT AS '
BEGIN
RETURN COALESCE($1,$2);
END;' LANGUAGE 'plpgsql';
You will have to do this for all supported data types unless you want to
put in a third parameter that would be the cast type

I know this functions, but I do not want to change the statements in my

So I want to make the functions with the Oracle names for compatibility.

You don't need to build any function for this, you have them ready:

Hi,
I'll try to switch from Oracle to postgres for some small applications.
Is it possible to build functions like Oracle's nvl or decode with pgplsql?
How can I make a function like nvl that works for every datatype?
Best regards,
Christian
