CREATE TYPE my_type AS ( user_ts_start My_start_timestamp, user_ts_end My_end_timestamp,
db_ts_start My_start_timestamp,
db_ts_end My_end_timestamp,
audit_record jsonb );
My_start_timestamp is a domain of timestamp with default as now().
My_end_timestamp is a domain of timestamp with default as infinite
May I use user_ts_start and/or db_ts_start has part of Primary Key of a table that contains a field of my_type?
to add an overall check constraint on the entire composite type, could be a valid approach to create a domain based on my_type and add a custom function to validate it? (check_my_type(VALUE)). In this way I've a dominan of composite type that contain others domain... what do you think?
thank's in advance
