Method _parse_raw_version_string

piccolo/engine/postgres.py:387–397

The format of the version string isn't always consistent. Sometimes it's just the version number e.g. '9.6.18', and sometimes it contains specific build information e.g. '12.4 (Ubuntu 12.4-0ubuntu0.20.04.1)'. Just extract the major and minor version numbers.
