If an OS write of the PostgreSQL page size has no chance of being partially persisted (a/k/a torn), I don't think full page writes are needed. That seems likely to be true if pg page size matches SSD sector size. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
