Re: insert a text file into a variable in order to insert into a bytea column - Mailing list pgsql-sql

Hi David,
Yes you're correct.  The problem is caused by the back-ticks (`)  Here is what I found in the docs about back-ticks

"Within an argument, text that is enclosed in backquotes (`) is taken as a command line that is passed to the shell.
Theoutput of the command (with any trailing newline removed) replaces the backquoted text."

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
thatseems to be working.  







​Or the "back-ticks" implementation...
