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)

	int covertToAmt(var l){
	var amt = 0;
	for (int i = 0, j=l.length-1; i < l.length; i++, j--) {
	amt+=((l[j]<<(i*8)));
	}
	return amt;
	}

	(dest + (2 i)) = ((*(src + i) &0xF0) >> 4) + 0x30;
