i have noticed it too.

Ubuntu 11.10
postgresql 9.1
pgadmin 1.14.1
compiled using gcc/g++, no additinional flags, only ./configure, make,
make install
rev: REL-1_14_1
show system objects - not enabled

example of SQL pane:

CREATE TABLE projects
( id serial NOT NULL, name text NOT NULL, handler text, CONSTRAINT projects_pkey PRIMARY KEY (id )
)
WITH ( OIDS=FALSE
);
ALTER TABLE projects OWNER TO smsgtwlive;

-- Trigger: RI_ConstraintTrigger_4601055 on projects

-- DROP TRIGGER "RI_ConstraintTrigger_4601055" ON projects;

CREATE CONSTRAINT TRIGGER "RI_ConstraintTrigger_4601055" AFTER DELETE ON projects FOR EACH ROW EXECUTE PROCEDURE
"RI_FKey_restrict_del"();

-- Trigger: RI_ConstraintTrigger_4601056 on projects

-- DROP TRIGGER "RI_ConstraintTrigger_4601056" ON projects;

CREATE CONSTRAINT TRIGGER "RI_ConstraintTrigger_4601056" AFTER UPDATE ON projects FOR EACH ROW EXECUTE PROCEDURE
"RI_FKey_restrict_upd"();
