Hi all
I have created following statement to get the ordered parameter list of
functions. I use UNNEST to get rows from array. This works fine but I am
not sure whether the ordering remains in the later use. Background is
PL/pgSQL to revoke grants to get a pristine start for granting. As the
order of the parameter is important, I should use a statement that
returns the properly ordered list of parameters. Maybe I did take a
wrong turn and one can achieve this simpler.
Suggestions are very welcome.
Kind regards Thiemo
