Well, I realize we want streaming archive logs, but there are still going to be people who are archiving for point-in-time recovery, and I assume a good number of them are going to compress their WAL files to save space, because they have to store a lot of them. Wouldn't zeroing out the trailing byte of WAL still help those people? -- Bruce Momjian <bruce@xxxxxxxxxx> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. + -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
