I meant verbosity, not error level. This quick test shows what I meant
-- but it doesn't work; the server log is altered as I expected (and does not
include the context lines), but not plpgsql's:

alvherre=# create function f() returns void language plpgsql as $$ begin raise info 'hello'; end $$;
CREATE FUNCTION
alvherre=# select f();
INFO: hello
f
---

(1 fila)

alvherre=# create function g() returns void language plpgsql as $$ begin perform f(); end $$;
CREATE FUNCTION
alvherre=# select g();
INFO: hello
CONTEXTO: SQL statement "SELECT f()"
función PL/pgSQL «g» en la línea 1 en PERFORM
g
---

(1 fila)

alvherre=# alter function g() set log_error_verbosity to 'terse';
ALTER FUNCTION
alvherre=# select g();
INFO: hello
CONTEXTO: SQL statement "SELECT f()"
función PL/pgSQL «g» en la línea 1 en PERFORM
g
---

(1 fila)

alvherre=# alter function f() set log_error_verbosity to 'terse';
ALTER FUNCTION
alvherre=# select g();
INFO: hello
CONTEXTO: SQL statement "SELECT f()"
función PL/pgSQL «g» en la línea 1 en PERFORM
g
