custom type %s.%s is not fully defined

Error message

custom type %s.%s is not fully defined

What it means

Returned by server.getTypeDetails in kingbase-go when the catalog row for the type was read but typisdefined is false — the type entry exists in the catalog in a partially-created/pending state (e.g. a failed CREATE TYPE left an undefined shell), so its details cannot be meaningfully rendered.

Solutions

1. Drop and recreate the type cleanly to clear the undefined shell entry
2. Check for an in-progress or failed type DDL transaction holding the entry
3. Inspect pg_type/sys_type for the typisdefined flag to confirm
