>     In <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
>, the same function name can be used for
     different function definitions as long as the number of arguments or their types
     differ. Tcl, however, requires all procedure names to be distinct.
     PL/Tcl deals with this by making the internal Tcl procedure names contain
     the object 
     ID of the function from the system table <TT
CLASS="STRUCTNAME"
>pg_proc</TT
> as part of their name. Thus,
     <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> functions with the same name
     and different argument types will be different Tcl procedures, too.  This
     is not normally a concern for a PL/Tcl programmer, but it might be visible
     when debugging.
