Data import as such, no matter how "heavy", shouldn't be a problem. The question is what are you doing that takes access-exclusive table locks frequently, and do you really need to do that? A quick look at the docs suggests that ALTER TABLE, REINDEX, or CLUSTER would be the most likely candidates for taking exclusive table locks. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
