Add benchmark for string (#168)

Closes GH-153

`SELECT` pattern parses text representation result.

`COPY` pattern parses binary representation result.

Integer pattern is faster that PostgreSQL but string pattern is slower
than PostgreSQL because we need to copy data when we generate record
batches with Apache Arrow C++'s array builder. We will improve
performance by avoiding the copy.
