Initialising Empty Structs in Rust

In C/C++, you can initialise a struct without giving values for any of the fields:

struct Point {
  float x;
  float y;
  float z;
};

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

• -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)
