Usage
timestamp9: nanosecond precision timestamp type for PostgreSQL
The timestamp9 extension provides a nanosecond-precision timestamp type stored as a 64-bit integer (nanoseconds since UNIX epoch).
CREATE EXTENSION timestamp9;
Data Type
The timestamp9 type supports timestamps from 1970-01-01 to 2262-04-12 with nanosecond precision.
Input Formats

SELECT '2019-09-19 08:30:05'::timestamp9;
-- Full nanosecond precision with timezone
SELECT '2019-09-19 08:30:05.123456789 +0200'::timestamp9;
-- Cast from bigint (nanoseconds since epoch)
SELECT 1568878205123456789::bigint::timestamp9;
Type Conversions
