Hi Ho John Lee,
I found one can in DBeaver upload an image into bytea data type column.
So my issue is gone; by using DBeaver I can upload images and also

I use python with psycopg2, for a table 'myimage_table' with columns
'label' and 'b' of type varchar and bytea something like this:
query = 'insert into myimage_table (label, b) values (%s, %s)'
imagelabel = 'some_label'

Hi,
I am a novice in postgresql language.
By reading the documentation about storing binary data in postgresql
database, I realize that that one can store images as binary data by
using bytea or BLOB data types.
I am running postgresql on Ubuntu 20.04.2 LTS and using pgAdmin4 in
Desktop mod
