Obviously, it was mostly my fault (I didn't think of the precedence of my operator at all), but I didn't find anything in the CREATE OPERATOR documentation about it either. From looking at the code, I think I understood that it has a very low precedence, but shouldn't it be specified in the documentation (so that at least distracted people like me think of precedence next time they create an operator :) ) ?

CREATE OPERATOR has nothing to say on the subject because operator precedences are hard-wired into the parser and can't be changed by CREATE OPERATOR. See http://www.postgresql.org/docs/8.4/static/sql-syntax-lexical.html#SQL-PRECEDENCE regards, tom lane ^ permalink raw reply [nested|flat] 2+ messages in thread
