Is this cast procedure is correct oid::regprocedure::text ?
When I try this, I get
ERROR:  cannot cast type regprocedure to text.

Here is a small bash script to grant execute on many functions. (There
are some strange error sometime, but I'm not able to reproduce the bug...)

########################################################
#!/bin/bash
#Usage: grantexfct schema groupe
schema=$1
groupe=$2


SQL="SELECT p.oid::regprocedure from pg_proc p
LEFT JOIN pg_namespace n ON p.pronamespace=n.oid
where n.nspname like '$schema';"
LIST=`psql -c "$SQL" -A -t -U postgres servweb`
echo $LIST


for fct in $LIST
do
echo $fct
SQL="GRANT EXECUTE ON FUNCTION $fct TO GROUP $groupe;"
psql -c "$SQL" -U postgres servweb
done


exit 0
########################################################

This is the pl/pgsql function. It is broken because I'm not able to cast
::regprocedure to ::text

Maybye there are others bugs...

########################################################
--grant_exec(SCHEMA,GROUP)
-- Grants execute on every functions of SCHEMA to group GROUP
--
DECLARE
   schem ALIAS FOR $1;
   grp ALIAS FOR $2;
   obj record;
   num integer;
BEGIN
   num:=0;
   FOR obj IN SELECT p.oid::regprocedure as funct
   FROM pg_proc p
   LEFT JOIN pg_namespace n ON p.pronamespace=n.oid
   where n.nspname like schem LOOP
   EXECUTE 'GRANT EXECUTE ON FUNCTION ' || schem || '.' ||
obj.funct ::text || ' TO GROUP ' || grp;
   num := num + 1;
   END LOOP;
   RETURN num;
END;

Any comment is welcome.
Thank you to everyone who has contributed to this "solution".
