418ec3207: it's better to do it like this,
else you have to drop and recreate the extension for each
permutation. tcn.spec only has one permutation at present,
so this doesn't speed it up any, but it's still a bad example.
PGFILEDESC = "tcn - trigger function notifying listeners"
ISOLATION = tcn
+ISOLATION_OPTS = --load-extension=tcn
ifdef USE_PGXS
PG_CONFIG = pg_config
setup
{
- CREATE EXTENSION tcn;
CREATE TABLE mytable (key int PRIMARY KEY, value text);
CREATE TRIGGER tcntrig AFTER INSERT OR UPDATE OR DELETE ON mytable
FOR EACH ROW EXECUTE FUNCTION triggered_change_notification(mychannel);
