query length limits - Mailing list pgsql-sql

Does Postgres have any limitations on
the length of queries?

E.g. is "select one,two,three,...thousand from one,two,three,...thousand where one = x and two is x and three is x and
...thousand = x" legal? 

I could test this of course, but I am curious about the real
limits imposed by the system, and any possible consequences,
plus any changes planned in the future which might affect
this issue.


Thanks,


Troy
