I thought someone up-thread said that in this case it wound up as bpchar; but I see that's not so: test=# select pg_typeof((select case when true then 'xxx' else 'a'::char(1) end)); pg_typeof ----------- character (1 row) All that's done is to strip off the length. I guess that since the "char" type is documented as being for internal use, these issues would only affect those who choose to write queries against catalog tables or use an internal type in their tables, so I guess it's not worth going to extremes to make it behave like char. Given all that, I'll conceed the point, and give a +1 for the error message. -Kevin
