/*
 * This file replaces upgrade-*.sql files that show what SQL commands are required to
 * upgrade from one version of WebCalendar to another.
 * This file was introducted in v1.9.12 as part of the new installer.
 * The intent of this file is that by default the SQL for the upgrade will be
 * in the 'default-sql' field.  However, if any database needs different SQL,
 * there should be a db-specific key in the array like 'postgres-sql' or 'sqlite3-sql'.
 * NOTE: Currently only tested with MySQL.
