OK, it seems I had some progress sanEtising my interactions with postgres and psql, its sql shell.

Once I create a database and a database user I no longer need to use the "postgres" linux account to run commands via su thanks to the "service file". This is a simple configuration file which holds dbname, dbuser, pass etc.:

# located at x/y/z.config
[myservice]
host=
port=
# above 2 can be left empty to denote unix socket connection
dbname=...
user=...
password=...

[download]

And then PGSERVICEFILE=x/y/z.config psql 'service=myservice'

I have also found that psql accepts a connection string like: sql 'postgresql://mydbuser:mypassword@host:port/mydbname' (host, port are optional, leave empty for unix socket connection)
