I didn't intend to invent a new heavy rule or tool. I just meant comments just like the existing function
descriptions,something like
/** Hook name: Authentication hook* Description: ...* Arguments: ...* Return value: ...* Note: ...*/

Me, too.

OK. Anyway, if we can see in the PostgreSQL documentation what hooks are available, it would be the best. I imagine
youmeant adding a new chapter under the part "V. Server Programming".
