The error I'm seeing:

Two ways to build a range:
select '[2024-02-18, 2024-02-20)'::tstzrange;
tstzrange
-----------------------------------------------------
["2024-02-18 00:00:00-08","2024-02-20 00:00:00-08")
or
select tstzrange('2024-02-18', '2024-02-20', '[)');
tstzrange
-----------------------------------------------------
["2024-02-18 00:00:00-08","2024-02-20 00:00:00-08")
See here:
https://www.postgresql.org/docs/current/rangetypes.html
for more information.
The function:
CREATE OR REPLACE FUNCTION new_event_session(p_event_id text, p_start_time
timestamptz,
p_end_time timestamptz,
p_sess_title text,
p_sess_desc text
) RETURNS text AS $$
DECLARE
v_session_id text;
BEGIN
INSERT INTO event_sessions(event_id,evt_sess_times)
VALUES(p_event_id,[p_start_time,p_end_time)) RETURNING evt_sess_id
INTO v_session_id;
// REST OF FUNCTION REMOVED FOR BREVITY
The table definition:
CREATE TABLE IF NOT EXISTS event_sessions ( event_id text NOT NULL,
evt_sess_id text NOT NULL PRIMARY KEY DEFAULT ksuid_pgcrypto_micros(),
evt_sess_times tstzrange NOT NULL,
evt_sess_inserted timestamptz not null default now(),
CONSTRAINT fk_evt_id
FOREIGN KEY(event_id)
REFERENCES events(event_id),
EXCLUDE USING gist (
event_id WITH =,
evt_sess_times WITH &&
)
);
N.B. I'm calling from Go, the library does not natively support tstzrange,
hence the need to break-out the input parameters.
Thanks !
