I can just give you (at the end of this answer) the DDL for the fields I
reported in the query, but they are enough because I tried the example I'm
giving you (with all tables empty and without FK, while in the original
database they had less than 50 rows each) and I got the same result (so, it
should be data independent - but I understand that you meant that the error
could be data type dependent, so I give you the - reduced - tables
definitions).
I expected that the error was data independent, because, as I told before, I
could not get the plan for the not-working query.
Version? In my previous message I told that I'm using 7.4-1 on cygwin
distribution. What other info do you need? How can I get them?
All I can think more than this is that I use a Windows XP O.S. and that I
got this error both using JDBC and using pgAdmin III (but it seems to me
that this is an error client-independent).
The other problem, however, as I asked before, is: where can I find the
documentation for this error (well, besides the source, of course)? are
there known limits in joining tables?
Thanks again
