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