Push enable/disable of notify and catchup interrupts all the way down
Tom Lane <tgl@sss.pgh.pa.us>
Push enable/disable of notify and catchup interrupts all the way down to just around the bare recv() call that gets a command from the client. The former placement in PostgresMain was unsafe because the intermediate processing layers (especially SSL) use facilities such as malloc that are not necessarily re-entrant. Per report from counterstorm.com.
