Actually, I thought the question was not about whether CREATE TABLE AS is documented, but about the specific point of it being the thing to use for this purpose in plpgsql: >> In that case, how could I create a temporary table from plpgsql? > CREATE [TEMP] TABLE foo AS SELECT ... > This is equivalent to SELECT INTO [TEMP] foo in regular SQL, and > does not change meaning in plpgsql. I have been thinking that our plain-SQL "SELECT INTO table" construct should be deprecated (and maybe eventually removed), since it really doesn't have much to do with the SQL-standard meaning of SELECT INTO: the spec contemplates INTO as introducing a list of scalar variables to be assigned to. plpgsql and ecpg both use this meaning for SELECT INTO. Would anyone object if I add text to the SELECT INTO ref page that points this out, and recommends CREATE TABLE AS as the preferred syntax? regards, tom lane
