Thread: pgsql: Support for ISO 8601 in the jsonpath .datetime() method
Support for ISO 8601 in the jsonpath .datetime() method The SQL standard doesn't require jsonpath .datetime() method to support the ISO 8601 format. But our to_json[b]() functions convert timestamps to text in the ISO 8601 format in the sake of compatibility with javascript. So, we add support of the ISO 8601 to the jsonpath .datetime() in the sake compatibility with to_json[b](). The standard mode of datetime parsing currently supports just template patterns and separators in the format string. In order to implement ISO 8601, we have to add support of the format string double quotes to the standard parsing mode.
