Based on a diff of defaults.sql, the following statements should be executed to enable the new permissions in beta2 (if you installed beta1).
Code:
insert into perm_server_group (server_id, id1, id2, perm_id, perm_value,perm_negated, perm_skip) values (0, 2, 0, "b_client_issue_client_query_command", 1, 0, 0);
insert into perm_server_group (server_id, id1, id2, perm_id, perm_value,perm_negated, perm_skip) values (0, 2, 0, "i_needed_modify_power_client_issue_client_query_command", 100, 0, 0);
insert into perm_server_group (server_id, id1, id2, perm_id, perm_value, perm_negated, perm_skip) values (0, 3, 0, "b_client_issue_client_query_command", 1, 0, 0);
insert into perm_server_group (server_id, id1, id2, perm_id, perm_value, perm_negated, perm_skip) values (0, 3, 0, "i_needed_modify_power_client_issue_client_query_command", 75, 0, 0);
You will also need to update the permissions for any existing virtual servers (if you want them to be able to use the new permissions). Basically, the below will grant the group with a group_id of 6 (which should be the group_id of the server admin group for the first virtual server) the permissions that would've been granted by default had you started with a fresh beta2 install.
If you want to double check the group_id (which you should), take a look at the groups_server table (the first virtual server has a server_id of 1). If you see a row that looks like this (all columns selected) "6, 1, 'Server Admin', 1", 6 is the group_id of the Server Admin group on virtual server 1 (server_id 1).
Code:
insert into perm_server_group (server_id, id1, id2, perm_id, perm_value, perm_negated, perm_skip) values (0, 6, 0, "b_client_issue_client_query_command", 1, 0, 0);
insert into perm_server_group (server_id, id1, id2, perm_id, perm_value, perm_negated, perm_skip) values (0, 6, 0, "i_needed_modify_power_client_issue_client_query_command", 75, 0, 0);
