What you are facing:

1) Bytea stores binary strings in the formats specified here:

https://www.postgresql.org/docs/current/datatype-binary.html

2) The database has no 'knowledge' of what those binary strings
represent. They could be an image, a PDF, a spreadsheet file, etc.

3) To achieve what you want you need some sort of client code that can
take the binary strings and convert them to the correct output. Then you
can match and display.
