Re: connecting to a differnt DB in PL/pgSQL

you should install dblink as Tomasz said. To do that:

cd ...../postgresql-7.3.2/contrib/dblink
gmake
gmake install

then you enter into psql to create the functions:
\i dblink.psql

then you try (change the params):

SELECT    *
FROM    dblink('host=localhost port=5432 dbname=franco user=admin password=1234',
'SELECT id, name FROM people')    AS (id INTEGER, people TEXT);

If you skip the values host, port, ..., the defaults will be used.
If it works in psql, it should work inside a function.
