Yeah. to_char() does not have any source for the TZ/TZH/TZM fields other than the prevailing value of the timezone parameter, so you really have to set that the way you want if you desire to use these format fields. As noted upthread, SET LOCAL together with a (dummy) "SET timezone" clause in the function definition can be used to get the effect of a function-local setting of the parameter. I don't know of another way to achieve that result above the C-code level. regards, tom lane
