No. There isn't a limit with regarding the selecting of data out
of PostgreSQL. But there currently is a record limit of around 8K
(generally speaking) in 7.0.x. So you could have a query, for
example, which appends 100K of string constants as apart of a
select. Anyway, that limit is scheduled to be removed in 7.1,
allowing you to store objects of an arbitrary size in the
database. This includes the excellent implementation of NUMERIC,
which performs arithmetic of arbitrary precision. Have a look at:
http://www.postgresql.org/projects/devel-toast.html
for details. I believe there might also exist some limitations
remaining in some of the interfaces, but I'm not quote sure. I
know that libpq, the C interface library, has had all query
length limits removed.
Hope that helps,
