Hi all. I'd like to understand how partitioning (actually table inheritance) works when the number of tables grows in the order of thousands. In my case, all child tables inherit also the indexes from the master one (as well as constraints). 1. How will change the performances in the case a relevant number of the child tables (10%) needs to be included in the actual query? Do the needed time and resource grow linearly (or what)? 2. How will work a PK on the master table in regards to the child tables? 3. Will a FK reference to the master table's PK be "redirected" to the proper child table? -- Vincenzo Romano NotOrAnd Information Technologies NON QVIETIS MARIBVS NAVTA PERITVS -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
