//
// The Default chosen Time Frame to calculate the pivot points is: 
//      Daily (D) if within intraday
//      Weekly (W) if within daily chart
//      Monthly (M) if within weekly chart

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
