Because the slave is the one connecting to the master and requesting the info it needs, the master get hurts very low -if any- for every standby so you can have effectivelly a lot of them. Still, the question remains... you really need so many standbys? -- Jaime Casanova www.2ndQuadrant.com Professional PostgreSQL: Soporte 24x7 y capacitación Phone: +593 4 5107566 Cell: +593 987171157 -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
