BIT BITSTRING variable-length strings of 1s and 0s

Bitstrings are strings of 1s and 0s. The bit type data is of variable length. A bitstring value requires 1 byte for each group of 8 bits, plus a fixed amount to store some metadata.

By default bitstrings will not be padded with zeroes. Bitstrings can be very large, having the same size restrictions as BLOBs.

Create a bitstring:

SELECT '101010'::BIT;

Create a bitstring with predefined length. The resulting bitstring will be left-padded with zeroes. This returns 000000101011:

SELECT bitstring('0101011', 12);
