>Description</H2
><P
> <TT
CLASS="COMMAND"
>CREATE TEXT SEARCH TEMPLATE</TT
> creates a new text search
template. Text search templates define the functions that implement
text search dictionaries. A template is not useful by itself, but must
be instantiated as a dictionary to be used. The dictionary typically
specifies parameters to be given to the template functions.
</P
><P
> If a schema name is given then the text search template is created in the
specified schema. Otherwise it is created in the current schema.
</P
><P
> You must be a superuser to use <TT
CLASS="COMMAND"
>CREATE TEXT SEARCH
TEMPLATE</TT
>. This restriction is made because an erroneous text
search template definition could confuse or even crash the server.
The reason for separating templates from dictionaries is that a template
encapsulates the <SPAN
CLASS="QUOTE"
>"unsafe"</SPAN
> aspects of defining a dictionary.
The parameters that can be set when defining a dictionary are safe for
unprivileged users to set, and so creating a dictionary need not be a
privileged operation.
