Good call. However, the following complains about the $ in $1. My
guess is that the SET command doesn't like anything but an integer to
be there. If I make it a string, the function gets defined, but at
runtime it complains that it is not an integer. If I try to cast the
string to '$1'::integer the function definition again fails with
syntax error.
CREATE OR REPLACE FUNCTION setlogtime(integer) RETURNS void AS $$
SET log_min_duration_statement = $1;
SHOW log_min_duration_statement;
$$ LANGUAGE SQL SECURITY DEFINER;
I tried variants '$1' and '$1'::integer as noted above.
How can I write this function?
