CREATE EXTENSION pg_rrule;Usage
pg_rrule: iCalendar RRULE recurrence rule type for PostgreSQL
The pg_rrule extension provides an RRULE data type for parsing and expanding iCalendar recurrence rules (RFC 5545).
CREATE EXTENSION pg_rrule;Parameter Extraction
-- Get frequency
SELECT get_freq('FREQ=WEEKLY;INTERVAL=1;WKST=MO;UNTIL=20200101T045102Z'::rrule);
-- WEEKLY
-- Get days of week (numeric array)
SELECT get_byday('FREQ=WEEKLY;BYDAY=MO,TH,SU'::rrule);
-- {2,5,1}Occurrence Generation
-- Generate occurrences from an RRULE
SELECT unnest(get_occurrences(
'FREQ=DAILY;INTERVAL=1;UNTIL=20200105T000000Z'::rrule,
'2020-01-01 00:00:00'::timestamp
));The get_occurrences() function expands RRULE definitions into concrete timestamp sequences, supporting both timezone-aware and naive timestamp parameters.
Dependencies
Requires libical for iCalendar standard compliance.
