Say my table looks like:
CREATE TABLE foo(status char(5), name char(5));
and I want to have a rule that does this:
CREATE RULE nf_foo AS
ON INSERT TO foo DO
NOTIFY new.status || '_' || new.name;
Any hints? My first attempt was to write a function:
CREATE FUNCTION bar(foo) RETURNS TEXT AS
'SELECT $1.status || ''_'' || $1.name;'
LANGUAGE 'sql';
and then change the last line of the rule to
NOTIFY bar(new);
but no luck. I would like to avoid writing a bunch of rules to process
each combination of 'status' and 'name' (at least they're each a limited
set!).
