Thread: question about pg_dump

I'm trying to upgrade from 6.3.  In doing this, I performed a pg_dump of
each database (pg_dump -o where the oid's matter).  I have one database
(which doesn't use oid info in the tables btw) that is around 40MB of
data.  The output file that created looks fine, but when I go to load the
data, it gets a portion of the way into loading and indicates that you
cannot exceed 20000 lines of input on a copy command.  Is there a way to
dump the database that it won't try more than 20000 lines at a time?  I
kept the 6.3 directory so dumping again is not a big deal.

You can just split the command into sections by editing the dump file
(assuming you have an editor that will cope ;-)):

    COPY table FROM stdin;
    blah blah
    blah blah
    \.
    COPY table FROM stdin;
    more more
    more more
    \.

COPY is really APPEND, it doesn't delete any tuples that were there,
so this should work.

Still, a 20K-line limit sounds awfully brain-dead to me.  And a quick
look at the source code (both 6.4.2 and current CVS) doesn't show any
such check unless I missed something.  What version are you using?
What's the exact text of the error message?
