Support for FF1-FF6 datetime format patterns
SQL Standard 2016 defines FF1-FF9 format patters for fractions of seconds in
jsonpath .datetime() method and CAST (... FORMAT ...) SQL clause. Parsing
engine of upcoming .datetime() method will be shared with to_date()/
to_timestamp().
This patch implements FF1-FF6 format patterns for upcoming jsonpath .datetime()
method. to_date()/to_timestamp() functions will also get support of this
format patterns as positive side effect. FF7-FF9 are not supported due to
lack of precision in our internal timestamp representation.
Extracted from original patch by Nikita Glukhov, Teodor Sigaev, Oleg Bartunov.
Heavily revised by me.
