Обсуждение: Broken PL/PgSQL for 7.0 beta 3?

The following code works under 6.5 and doesn't work in 7.0 beta 3. Comments?


------------------snip---------------------------------------
create table paths ( pathnum  serial, pathname text );


CREATE FUNCTION plpgsql_call_handler () RETURNS OPAQUE AS          '/opt/brupro/pgsql/lib/plpgsql.so' LANGUAGE 'C';

CREATE TRUSTED PROCEDURAL LANGUAGE 'plpgsql'          HANDLER plpgsql_call_handler          LANCOMPILER 'PL/pgSQL';
      
 
/*********************************************************** This function makes handling paths MUCH faster on

CREATE FUNCTION get_path (text) RETURNS integer AS ' DECLARE       retval integer;   BEGIN       select pathnum into
retvalfrom paths where pathname = $1 ;       if not found then          insert into paths ( pathname )values ( $1 ) ;
      select pathnum into retval from paths where pathname = $1 ;       end if ;       return retval ;   END;

Please define "doesn't work".  I get (starting with a virgin paths table)

tpc=# select get_path('/etc');get_path
----------       1
(1 row)

tpc=# select get_path('/etc');get_path
----------       1
(1 row)

tpc=# select get_path('/etcz');get_path
----------       2
(1 row)

tpc=# select get_path('/etcz');get_path
----------       2
(1 row)

tpc=# select get_path('/etc');get_path
----------       1
(1 row)

which seems to be the intended behavior.

It might help to know what platform/compiler you are using, too.
