Error in dbConnect(): linux socket location moved

[helmingstay]

I'm running Postgres 15 and the current CRAN RPostgres on debian 12.
When I do:

> con <- dbConnect(Postgres())

I get the following:

Error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory
        Is the server running locally and accepting connections on that socket?

I confirmed via psql that the database is running and accessible with current user.
Some poking around:
$ netstat -nlp | grep 5432
shows the socket at /var/run/postgresql/.s.PGSQL.5432

I was able to get a successful dbConnect() after doing:
$ ln -s /var/run/postgresql/.s.PGSQL.5432 /tmp
