When inserting a bunch of entries I simply get the error message ERROR: value for domain po.email violates check constraint "email_check" SQL state: 23514 When inserting 1000+ entries in a batch, finding the exact entry with the problem is noticeably harder than with other error types. For example when a column should be a uuid but you pass in 'Mary had a little lamb', the error message tells you what the invalid value is as well as the column name you're trying to put it into. Are there any quick hacks floating around out there to solve or at least mitigate this?Is it a deferred constraint? Plain ole domain CHECK constraint. CREATE DOMAIN po.email AS varchar CHECK (VALUE IS NULL OR (po.length_in(VALUE, 1, 254) AND NOT po.email_expanded(VALUE) IS NULL));where "po" is another schema, po.length_in(...) is an IMMUTABLE range check, and po.email_expanded(...) is a function returning a record. Same behavior happens if I remove the functions and define the check constraint in place. The only info returned in a bulk insert is the name of the violated check constraint, aka email_check.
The blunt force answer is to not use bulk inserts. Try COPY; it's good at saying which record throws an error.
