I created a function that does some heavy string manipulation, so I needed to use pl/perl rather than pl/pgsql.
I'm not experienced in perl, but the function works well when used as an independent perl subroutine - it depends only on its arguments. I use the Encode package (in postgresql configuration).
But my use of the "pack" function causes a Safe error. Apparently "pack" and "unpack" are in the operator mask.
Is there any way to remove them from that mask? I don't want to use pl/perlu - it's too unsafe, I think, and its running environment is different.
