Bug reference: 13897
Logged by: Arthur Lewis
Email address: arthur.lewis@hypermediasystems.com
PostgreSQL version: 9.3.10
Operating system: Ubuntu Linux 14 (32 bit)
Description:
In the manual (http://www.postgresql.org/docs/9.3/static/app-psql.html) it
says in order to insert a file into the database all you do is the
following:
testdb=> \set content `cat my_file.txt`
testdb=> INSERT INTO my_table VALUES (:'content');
The manual also says:
Within an argument, text that is enclosed in backquotes (`) is taken as a
command line that is passed to the shell. The output of the command (with
any trailing newline removed) replaces the backquoted text.
I have a file called my_file.txt and it has 53604 bytes. When I do this
testdb=> \set content `cat my_file.txt`
testdb=> select length(:'content');
length
--------------
53603
Because of back-quotes I've just lost a byte (a trailing newline) and the
original file has been changed.
If there is a better way than using back-quotes please let me know.
