Marc Balmer ([EMAIL PROTECTED]) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
create table xy as select a,b from t_a left join t_b on cond fails in PL/pgSQL

Long Description
A SQL statement "create table t2 as select a,b from t_a left join t_b on <condition>;" 
works as expected when entered in psql but fails if it is part of PL/pgSQL function.

If executed in a PL/pgSQL function, the result table t2 will be created with columns a 
and b but only the values of a are inserted, column b remains empty in all rows.

Sample Code
-- works in psql, fails in PL/pgsql

create table datum (datum date);
create table termin (datum date, titel varchar(64), i integer);

create table t2 as select datum.datum,termin.titel from datum              
  left join termin on datum.datum >= termin.datum
  and ((datum.datum - termin.datum) % i = 0)
  and (enddatum >= datum.datum or enddatum = null);
