Re: pg_dump of table including check rule fails to restore

Further to my original message I realise that the problem was due to the
text of the rule still referring to columns, src_section_id and
dst_section_id by their original names, parent_section_id and
child_section_id respectively. So the nature of the bug changes to that
pg_dump does not correctly export CHECK rules where the name of the
column(s) referred to has changed. Now IMHO that is somewhat subtle.

Subject: pg_dump of table including check rule fails to restore


Hi

I have a schema which includes one table with a CHECK constraint. After the
schema is dumped (with pg_dump) as ascii text attempts to recreate it using
the psql -f <filename> command cause this one table, called navigaion, to
fail to create. This is using postgresql 7.3.3 on Redhat 9.0.  The fragment
of the dump is below. Is there a cure for this problem?

regards

Lewis
