Tom Lane 3651a3e6fb Support the syntax ... CREATE AGGREGATE aggname (input_type) (parameter_list) along with the old syntax where the input type was named in the parameter list. This fits more naturally with the way that the aggregate is identified in DROP AGGREGATE and other utility commands; furthermore it has a natural extension to handle multiple-input aggregates, where the basetype-parameter method would get ugly. In fact, this commit fixes the grammar and all the utility commands to support multiple-input aggregates; but DefineAggregate rejects it because the executor isn't fixed yet. I didn't do anything about treating agg(*) as a zero-input aggregate instead of artificially making it a one-input aggregate, but that should be considered in combination with supporting multi-input aggregates.		2006-04-15 17:45:46 +00:00
