proper(though generic client APIs may use that term), so I presume you mean to store the contents in a "bytea" typed
column. You could also convert the binary to a encoded text compatible type (e.g., base64) and use a text field
instead.

Something like this:

INSERT INTO images(image) VALES( loadfile( /home/igor/my_image) );

Looking to run it from gAdmin in the Terminal.

Thank you.
