/*

 * The configuration sync is split into 4 parts for each table:

 * 1) proxyconfig_prepare_rows()

 *    Renames rename_field to '#'||rename_field for all rows to be updated. It's done to avoid

 *    possible conflicts when two field values used in unique index are swapped.

 *    Resets reset_field to null for all rows to be deleted or updated. It's done to avoid

 *    possible foreign key violation when rows in self referencing table are updated or deleted.

 *    The changed fields are marked as updated, so during update processing the correct values

 *    will be assigned to them.

 *

 * 2) proxyconfig_delete_rows()

 *    Deletes all existing rows within scope that are not present in received table data. The scope

 *    is limited to received hosts when partial updates are done.

 *

 * 3) proxyconfig_insert_rows()

 *    Inserts new rows that were not present in database.

 *

 * 4) proxyconfig_update_rows()

 *    Update changed fields.

 *

 * When processing related tables (for example drules, dchecks) the prepare and delete operations are

 * done from child tables to master tables. The insert and update operations are done from master

 * tables to child tables. This is done to avoid child rows being removed with cascaded deletes and

 * have parent rows updated/inserted when updating/inserting child rows.
