Eyeball examination of a dump file shows that we only compress table-data entries, and don't for example waste time firing up the compressor to process a function body. It's possible that it'd be worth trying to have some lower limit on the amount of data in a table before we bother to compress it, but I bet that it wouldn't make any difference on your databases ... regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
