The documentation indicates that bytea will -store- binary data
The problem is getting the data into the column through SQL.
The Postgresql SQL is character data only (side note: what about unicode?
is this USASCII only?). You cannot just wrap your binary stream in a pair
of quotes and off you go. You must encode before saving and decode after
retrieving. The encoded form is stored in the column.
What I have not figured out is how to pass my data to encode.
This is a builtin function but it doesn't take a filename so how can
you use it!
At least with base64 I have ample libraries and can convert my data
before sending to sql or after receiving from sql. It becomes my
application's issue. Mind, this bloats the data considerably.
escape is less bloat but I have to recreate the encode/decode in my app,
so far as I see.
