Обсуждение: Problem with PL/pgSQL

   Hi

   I try to create the next function:

create function ttt() RETURNS OPAQUE AS '
BEGIN
RAISE EXCEPTION "Hello"
END' language 'plpgsql';

The result is:

ERROR:  Unrecognized language specified in a CREATE FUNCTION: 'plpgsql'.  
Recognized languages are sql, C, internal and the created procedural languages.

   I have postgres SQL ver. 6.5.2. 

   What's going on?

You need to do createlang on the table, like so:

$ createlang plpgsql test

Where test is the database.

You didn't install plpgsql into your database.  It's optional (just
in case a dbadmin doesn't want it available for some reason).
See the createlang script.

   As  the  message  says, only the created procedural languages   can be recognized.  You haven't enabled the language
and  it   isn't installed by default.  Use
 
       createlang <dbname>
   to  install  it  in  your  database. If you install it in the   template1 database, than  all  subsequent  created
databases  automatically inherit this.
