How can I use LEFT JOINS with postgresql?

Is there a command to do LEFT JOINS with postgresql?

Thanks

Upgrade to 7.1 (7.1.3 is the latest I think)
this allows you to use syntax like:

SELECT y.bar, x.foo
FROM tbly y
LEFT JOIN tblx x ON x.id = y.xid

I have followed the instructions in the Bruje Momjian´s book to register a
function, and i got this message:

 ERROR:/load of file /home/postgres/ctof.so failed: /home/postgres/ctof.so
ELF file´s phentsize not the expected size.

What is going on? I have tried to get more documentation about how to use C
functions in PostgreSQL, but I cant.

 Many thanks in advance
