Connects to the PostgreSQL database backend of timeseriesdb. This function is convenience wrapper around DBI's dbConnect. It's less general than the DBI function and only works for PostgreSQL, but it is a little more convenient because of its defaults / assumptions.

db_connection_create(
dbname,
user = Sys.info()[["user"]],
host = "localhost",
passwd = NULL,
passwd_from_file = FALSE,
line_no = 1,
passwd_from_env = FALSE,
connection_description = "timeseriesdb",
port = 5432
)

## Arguments

dbname

character name of the database.

user

character name of the database user. Defaults to the user of the R session. this is often the user for the database, too so you do not have to specify your username explicitly if that is the case.

host

character denoting the hostname. Defaults to localhost.

passwd

character password, file or environment name. Defaults to NULL triggering an R Studio function that asks for your passwords interactively if you are on R Studio. Make sure to adapt the boolean params correspondingly.

passwd_from_file

boolean if set to TRUE the passwd param is interpreted as a file location for a password file such as .pgpass. Make sure to be very restrictive with file permissions if you store a password to a file.

line_no

integer specify line number of password file that holds the actual password.

passwd_from_env

boolean if set to TRUE the passwd param is interpreted as the name of an environment variable from which to get the password

connection_description

character connection description describing the application that connects to the database. This is mainly helpful for DB admins and shows up in the pg_stat_activity table. Defaults to 'timeseriesdb'. Avoid spaces as this is a psql option.

port

integer defaults to 5432, the PostgreSQL standard port.
