You've already been pointed to the workaround backward-compat option.

What's happening here is that you're doing an implicit inner join. Your 
query is being interpreted by PostgreSQL as if you wrote:


select * from table1, othertable where table1.key=othertable.key;

though I prefer to write it as the IMO more readable:

select * from table1 INNER JOIN othertable ON table1.key=othertable.key;


This behaviour isn't supported anymore partly is because it's way too 
easy to write:


select * from table1 where table1.key=typotable.key;

and get confusing error messages or, if `typotable' exists, confusing 
query results. I'm pretty sure there were more reasons too, but I wasn't 
really active on the lists when that was going on.


It's also really confusing when reading a query.

So - as already pointed out, you will need to re-write your queries to 
add the required tables to the from clause.

Short term see here for config setting in postgresql.conf that can revert the 
behavior.
http://www.postgresql.org/docs/8.3/interactive/runtime-config-compatible.html#RUNTIME-CONFIG-COMPATIBLE-VERSION

Long term, change the queries :)
