RECREATE FUNCTION funcname

  {<psql_function> | <external-module-body>}

!! See syntax of CREATE FUNCTION for further rules !!

The RECREATE FUNCTION statement creates a new stored function or recreates an existing one.If there is a function with this name already, the engine will try to drop it and then create a new one.Recreating an existing function will fail at COMMIT if the function has dependencies.

Note	Be aware that dependency errors are not detected until the `COMMIT` phase of this operation.

After a procedure is successfully recreated, existing privileges to execute the stored function and theprivileges of the stored function itself are dropped.
