I want to uniquely identify some objects in DB with the shortest base64 string. Functions get_bit and set_bit number bits from the right within each byte; for example bit 0 is the least significant bit of the first byte, and bit 15 is the most significant bit of the second byte. Is there a SQL function in Postgres to simply convert a bytea into a binary string representation? PostgreSQL bytea to Base64 like SQL Server. 1. com > wrote: > I have been experimenting with some base64 encoding/decoding implementation.
