notes "
The Vlang library directory is group _developer writable. You need to be a member of the
_developer group to use Vlang. If you are not, run:

sudo dscl . append /Groups/_developer GroupMembership <username>

Optionally, to use the V PostgreSQL module, install PostgreSQL and set the POSTGRESQL_VERSION
environment variable. For PostgreSQL 14:

export POSTGRESQL_VERSION=14
