+ Reconstructs the CREATE POLICY statement from the
+ system catalogs for a specified table and policy name. The result is a
+ comprehensive CREATE POLICY statement.
+
+ Most of the functions that reconstruct (decompile) database objects have an
+ optional pretty flag, which if
+ true causes the result to be
+ pretty-printed
. Pretty-printing adds whitespace for
+ legibility. Passing false for the
+ pretty parameter yields the same result as omitting
+ the parameter.
