My bad, the table I was looking (8.7) at had the first column as the
decimal representation and I did notice that the numbers changed as they
moved right.
Is there a way for bytea to take a hex number, or do I need to convert the
bit stream to octal numbers?
to_hex()?
to_hex() produces the text representation of the hex digits, not the actual
bytes with those values.
What the OP wants is to conveniently represent the bytestream to send to the
bytea column. They're looking for an escape sequence to embed into a text
representation that will map to the exact byte contents to insert, not a text
representation of that representation.
Say,
Also supported are \digits, where digits represents an octal byte value, and
\xhexdigits, where hexdigits represents a hexadecimal byte value. (It is your
responsibility that the byte sequences you create are valid characters in the
server character set encoding.)

Amazing how useful the docs are.
