  1. Subqueries?

    Aleksey Dashevsky <postgres@luckynet.co.il> — 1998-09-04T07:15:19Z

    hi, hackers!
    do you plan some improvments on subqueries?
    Unfortunately, in v6.3.2 they often works very slowly, and thus
    are useful only on quite small tables :-(
    
    Thanky you
    Aleksey.

    Nothing...
    If you use IN then try to rewrite your queries with EXISTS
    if possible...

    This is the first report of subquery slowness I have heard.  We have
    fixed a problem where using an oid in the subquery caused a loop, but
    other than that, everything seems fine.  How about sending us some
    queries that are slow, and perhaps we can suggest something.
