WARNING IN serverlog file

Hi all ,

When I call a function within other function I get this warning in the
serverlog file
<code>
WARNING: BEGIN: already a transaction in progress
WARNING: BEGIN: already a transaction in progress
</code>
I am calling the function within other function with following syntax
<code>
all blah blah of function
DECLARE
data_call TEXT ; -- text data to be retrived
BEGIN
data_call := function_called();
end;
some more blah plpgsql;
</code>

I would like to know ?
1. Is this warning ignorable as my function

function_called();
when executed as stand alone does not generate this warning in the
srverlog file
Also when i comment the function function_called() then also no such
warning is encountered

2. Why this warning generated when all syntax is correct in the function's
??

Loads of thanks in advance if you only read.

Loads of humble thanks in advance if you read and reply .

Regards,
V Kashyap
