Here's a simple one:

alvherre=# select version();
                                          version
--------------------------------------------------------------------------------------------
 PostgreSQL 8.0.1 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.3.5 (Debian 1:3.3.5-12)
(1 fila)

alvherre=# create function test_syntax() returns void language plpgsql as 'begin zelect 1; return; end';
CREATE FUNCTION
alvherre=# select test_syntax();
ERROR:  error de sintaxis en o cerca de «zelect» en el carácter 1
QUERY:  zelect 1
CONTEXT:  PL/pgSQL function "test_syntax" line 1 at SQL statement
LINEA 1: zelect 1
         ^
alvherre=#


One would think that this is a pretty obvious syntax error ...
