inner join

hello

I've been trying to do a natural inner join with postgresql. However,
when I try to do that I loose my connection to the database.

Anybody had this same problem and knows how to fix it? Or at least
have somebody found a work around?

Thanks

The "inner join" syntax support in 7.0 is really just beta-quality
code; it's got a few bugs.  I'd suggest writing the query without
using inner join syntax, ie plain old
    SELECT ... FROM a,b WHERE a.x = b.x;

JOIN syntax will work a lot better in 7.1.

Can you post a sample (w/CREATE TABLE, INSERT data, and
SELECT statements.) This will help us debug the problem.

What are the reasons (other than useability ;-)) for using one rather
than the other?

Thanks.
