In general, I don't want to merge any performance optimizations without a benchmark that shows the improvement. That's especially true in this case because the text format was chosen on purpose. PostgreSQL (at least historically) has a significant performance penalty when returning text-like types as binary. See https://github.com/jackc/pg_text_binary_bench. |
