For example, with the default values, a table with 1 million rows will need to have more than 200,050 dead rows before an autovacuum starts ((1000,000 x 0.2) + 50). Theres an abundance of flags available for use when working with psql, but lets focus on some of the most important ones, then how to connect: -h the host to connect to-U the user to connect with-p the port to connect to (default is 5432) psql -h localhost -U username databasename.
