Re: insert a text file into a variable in order to insert into a bytea column

postgres=> \set stext `cat file.txt`
postgres=> select octet_length(:'stext');
octet_length
--------------
53603

in my shell I did the following:
$ ls -l file.txt
-rw-rw-r-- 1 alewis alewis 53604 Jan 27 08:30 file.txt

I'm still one byte short. So the problem has to be either the \set command chomping it or cat. I just tested cat and that seems to be working.

Hmm, well there went that theory;)

What happens if you do?:

select octet_length(:'stext');
