将oracle迁移到Postgresql UTL_FILE EXCEPTIONS

Question

I have the same situation as described in this post: Porting Oracle procedure to PostgreSQL (exception codes from orafce for utl_file module)

I'm migrating from oracle to postgres with ora2pg and I`m trying to correct the syntax of the exception handling that I have for 'utl_file'. Someone commented a solution in the other post but I didn't understand how to properly apply it.

I have the next code :

   V_Step := 1;

    FOR Rec_Report IN C_Report LOOP

      V_Counter := V_Counter + 1;

      -- Header
      IF V_Counter = 1 THEN

         -- Open File
        V_File_Type := UTL_FILE.FOPEN(V_Dir_Name, V_File_Name,'w');

        V_Step := 2;

        bl_create_flat_file_pg.open_html(V_File_Type);
         .......
         .......
         .......

          V_Step :=10

EXCEPTION
when UTL_FILE.INVALID_PATH then
PERFORM control_reports_pg.send_error_mail('invalid_path 
V_Step'||V_Step,C_Function_Name);
PERFORM UTL_FILE.FCLOSE(V_File_Type);

when UTL_FILE.INVALID_MODE then
PERFORM control_reports_pg.send_error_mail('INVALID_MODE  
 V_Step'||V_Step,C_Function_Name);
     PERFORM  UTL_FILE.FCLOSE(V_File_Type);

Therefore for every step I have a piece of code like this that handles the exception. I get a syntax error : ERROR: syntax error at or near "UTL_FILE".

Please help...

I've been writing PL/SQL for quite some time and I've never come across the PERFORM imperative. If this code is to run on an Oracle instance, then I would simply the remove the two "PERFORM" strings.

If this is supposed to run on a POSTGRES instance, then I'd not expect UTL_FILE to exist. If it does exist, then maybe the user running the code has not been granted permissions to execute UTL_FILE.
