>   The catalog <TT
CLASS="STRUCTNAME"

   <SPAN
CLASS="QUOTE"

> information for procedural languages.
   A template for a language allows the language to be created in a
   particular database by a simple <TT
CLASS="COMMAND"
>CREATE LANGUAGE</TT
> command,
   with no need to specify implementation details.
  </P
><P
>   Unlike most system catalogs, <TT
CLASS="STRUCTNAME"
>pg_pltemplate</TT
>
   is shared across all databases of a cluster: there is only one
   copy of <TT
CLASS="STRUCTNAME"
>pg_pltemplate</TT
> per cluster, not
   one per database.  This allows the information to be accessible in
   each database as it is needed.
