Friendly greetings ! According to : http://developer.postgresql.org/pgdocs/postgres/storage-page-layout.html Every table and index is stored as an array of pages of a fixed size (usually 8 kB, although a different page size can be selected when compiling the server). Is there any usage/interest to change this page size ? thank you. -- F4FQM Kerunix Flan Laurent Laborde -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
