7.4.6 to 8.2.5 - ' changes to $_$

[Steve Clark <sclark@xxxxxxxxxxxxx>]

function from 7.4.x postgres

CREATE FUNCTION update_dns(text, text) RETURNS integer
     AS 'UPDATE domain_details SET domain = $2 WHERE domain = $1;
     DELETE from domains where domain = $1;
     SELECT 1 AS ignore;'
     LANGUAGE sql;

I load it into 8.2.5 - then dump it out and it is changed to


CREATE FUNCTION update_dns(text, text) RETURNS integer
     AS $_$UPDATE domain_details SET domain = $2 WHERE domain = $1;
     DELETE from domains where domain = $1;
     SELECT 1 AS ignore;$_$
     LANGUAGE sql;

notice $_$ where the single ' use to be.

Is there some way to keep this from happening?

The reason is we have systems in the field that have configuration 
information stored in 7.4.x.
We want to upload that db info load it into an 8.2.5 db massage it 
then send it back to the unit
in the field. I realize there are things I am going to have to fix up 
in the 8.2.5 dump to be able to load
it back into the 7.4.x db but I want to minimize that as much as possible.

We have some units in the field running 8.1.3 and it does not change 
the ' to $_$.


Thanks,
Steve
