Hi, I was looking at the VarBit data structure and found out that instead of storing the number of bits in four bytes, we can save the number of bits that are valid in the last byte. Since we already store the number of bytes in Varlena Header, we can calculate the number of valid bits by doing the small math. ( (No. of bytes-1) * 8 + valid bits in the last byte). This would save atleast 8 bytes for someone, who is using the varbit data type using less than 24 bits.
Waiting for comments. Thanks, Gokul.
