To get correct and consistent results on a replication, the

SQLite doesn't support replication so it doesn't have such problem.
Btw, MySQL calls a master server source server now.
table_exits()
method should be executed on write link (usually the source server) for DB_MySQL
/ DB_MySQLi
/ MysqlPdoDbDriver
, whereas on a random link now. The reason is explained at https://community.mybb.com/thread-119212...#pid863290 (limited access).DB_MySQL
, DB_MySQLi
and MysqlPdoDbDriver
using query()
without writeQuery
specified for table_exits()

DB_PgSQL
and PostgresPdoDbDriver
both using write_query()
for table_exits()
, which is the right way I think:https://github.com/mybb/mybb/blob/mybb_1...l.php#L651
