should I also say something about DELETE and UPDATE in here?
It's much easier to enumerate queries that are allowed. I would say that it restricts permissions to all types of queries except readonly queries (like SELECT and equivalent queries), and queries that modify only session context (like USE and (for readonly=2) SET and CREATE TEMPORARY TABLE). Queries like EXISTS, DESCRIBE, SHOW PROCESSLIST, etc are equivalent to SELECT, because they just do select from system tables. EXPLAIN is also equivalent to SELECT.

I combined sections and (I think!) simplified. |

@tavplubix ,should I also say something about DELETE and UPDATE in here? These (I believe) require ALTER, so need allow_ddl=1.
