The current implementation uses two loops, first one to find out where digits start and second one to loop over the digits. The modified implementation starts at the end and loops till digits end. It is a bit faster than baseline.

Reading through pgx docs and came across this while exploring. Curious. Could those performance gains be from caching on the postgres side? Or does the testsuite have a way to reset? |

@acelinkio The benchmark is only testing parsing a command tag. There is no PostgreSQL server in those tests. |
