    Sure sounds to me like what you are setting is something client-side,
    not the server's log verbosity.  It works for me:

    regression=# do $$ declare x int; y int = 0; begin x := 1/y; end$$;
    psql: ERROR:  division by zero
    CONTEXT:  PL/pgSQL function inline_code_block line 1 at assignment
    regression=# set log_error_verbosity = terse;
    SET
    regression=# do $$ declare x int; y int = 0; begin x := 1/y; end$$;
    psql: ERROR:  division by zero
    CONTEXT:  PL/pgSQL function inline_code_block line 1 at assignment

    after which I see this in the postmaster log:

    2019-04-22 16:40:38.300 EDT [25788] ERROR:  division by zero
    2019-04-22 16:40:38.300 EDT [25788] CONTEXT:  PL/pgSQL function
    inline_code_block line 1 at assignment
    2019-04-22 16:40:38.300 EDT [25788] STATEMENT:  do $$ declare x int;
    y int = 0; begin x := 1/y; end$$;
    2019-04-22 16:40:51.654 EDT [25788] ERROR:  division by zero
    2019-04-22 16:40:51.654 EDT [25788] STATEMENT:  do $$ declare x int;
    y int = 0; begin x := 1/y; end$$;

    Note that this changed the server log verbosity but *not*
    what was displayed on the client side.

    (BTW, if you want to get rid of the statement logging as well,
    see log_min_error_statement.)

    Also note that adjusting log_error_verbosity on the fly
    like this requires being superuser, which isn't really
    a good way to run in production.  I'd expect though that
    you could apply it with ALTER USER SET.

I am running it differently - explicitly raising a LOG level message, not an ERROR.  The line of interest is the following:

do $$
......
raise log 'pruned % rows from table', rows;
...

Even run as a superuser, it doesn't work. I have run it just as you did above - setting it client side.  Also done it on a per-role basis and it didn't work.

I tried to replicate your example and could not.

Questions:

1) Postgres version?

2) What is the actual message  you are seeing in the log?


Thanks,
Jeremy
