Function	Description
expr1 & expr2	Returns the result of bitwise AND of `expr1` and `expr2`.
base << exp	Bitwise left shift.
base >> expr	Bitwise (signed) right shift.
base >>> expr	Bitwise unsigned right shift.
expr1 ^ expr2	Returns the result of bitwise exclusive OR of `expr1` and `expr2`.
bit_count(expr)	Returns the number of bits that are set in the argument expr as an unsigned 64-bit integer, or NULL if the argument is NULL.
bit_get(expr, pos)	Returns the value of the bit (0 or 1) at the specified position. The positions are numbered from right to left, starting at zero. The position argument cannot be negative.
getbit(expr, pos)	Returns the value of the bit (0 or 1) at the specified position. The positions are numbered from right to left, starting at zero. The position argument cannot be negative.
expr1 | expr2	Returns the result of bitwise OR of `expr1` and `expr2`.
~ expr	Returns the result of bitwise NOT of `expr`.
