Hi, Since [1] walsender (not receiver as commit message says) can execute SQL queries. While doing some testing of [2] I noticed that SQL queries in walsender get stuck if parallelism is used - I have not investigated why that is yet, but it surely is an issue. On first blush I'd suspect that some signalling is not wired up correctly (cf. am_walsender branches in PostgresMain() and such).
This'd be easier to look at if the fairly separate facility of allowing walsender to execute SQL commands had been committed separately, rather than as part of a fairly large commit of largely unrelated things. Greetings, Andres Freund [1] https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=7c4f52409a8c7d85ed169bbbc1f6092274d03920 [2] http://archives.postgresql.org/message-id/30242bc6-eca4-b7bb-670e-8d0458753a8c%402ndquadrant.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
