Tim Nieradzik commented on CALCITE-5619:
----------------------------------------
On macOS, the `ROOT` locale behaves incorrectly:
@ (new SimpleDateFormat("EEE", Locale.ROOT)).format(new Date());
res4: String = "Sat"
@ (new SimpleDateFormat("EEEE", Locale.ROOT)).format(new Date());
res5: String = "Sat" // should be "Saturday"
@ Locale.ROOT
res1: Locale =
This is covered by `testToChar`.

> PostgreSQL has three to_char() functions:
> {{to_char ( timestamp, text ) → text}}
> {{to_char ( interval, text ) → text}}
> {{to_char ( numeric_type, text ) → text}}
> The following query cannot be parsed because the first to_char() function is
> not supported:
> {{select to_char(current_timestamp, 'YYYY-MM-DD HH24:MI:SS.MS TZ')}}
