Shifts the string operand bits to the left, filling with zeros to produce a string of the same length.
A left-shifted bitstring.
The behaviour of LShift is closer to what one would expect from dealing with PostgreSQL bit-strings than in using the same operations on integers in .NET
In particular, negative operands result in a right-shift, and operands greater than the length of the string will shift it entirely, resulting in a zero-filled string.
