to_hex() takes in integer or bigint and returns a hexadecimal string equivalent. But there is also, perhaps better, encode() and decode() which convert string to either base64, hex, or "escape" codes.

PHP has functions "bin2hex()" and "hex2bin()", and I have to deal with the results in PostgreSQL.
These functions "Returns an ASCII string containing the hexadecimal representation ofstr. The conversion is done byte-wise with the high-nibble first" and "Decodes a hexadecimally encoded binary string". Basically you can take binary data and each byte becomes two hexadecimal characters.
Is there anything in PostgreSQL that can do this already? I'm sure I can work it out but it can't hurt to ask first.
