Function doParseDArrayFromString

pkg/sql/sem/tree/parse_array.go:215–258

doParseDArrayFromString does most of the work of ParseDArrayFromString, except the error it returns isn't prettified as a parsing error. The dependsOnContext return value indicates if we had to consult the ParseContext (either for the time or the local timezone).
