The lookaside memory configuration for a database connection can only be changed when that connection is not currently using lookaside memory, or in other words when the "current value" returned by sqlite3_db_status(D,SQLITE_DBSTATUS_LOOKASIDE_USED,...) is zero. Any attempt to change the lookaside memory configuration when lookaside memory is in use leaves the configuration unchanged and returns SQLITE_BUSY.

However, since SQLite version 3.35.0, TEMP triggers are still allowed even if this option is off. So, in other words, this option now only disables triggers in the main database schema or in the schemas of ATTACH-ed databases.

SQLite does not make a copy of the new main schema name string, so the application must ensure that the argument passed into this DBCONFIG option is unchanged until after the database connection closes.

The SQLITE_DBCONFIG_ENABLE_QPSG option activates or deactivates the query planner stability guarantee (QPSG). When the QPSG is active, a single SQL query statement will always use the same algorithm regardless of values of bound parameters.
