Good Morning All,
I am using PostgreSQL 9.3 on Linux Rehat...
I'm trying to insert an image (.png format) into a table of flags. I've tried the following but keep getting errors.
CREATE TABLE FLAGS (country_code text, flag bytea);
INSERT INTO flags VALUES ('AD', pg_read_file('/home/flags')::bytea);
Get the following error:
ERROR: absolute path not allowed
*********ERROR*************
ERROR: absolute path not allowed
SQL State: 42501
Any assistance would be greatly appreciated.

If the image is on the computer where the SQL client is running, pg_read_file() can not be used
because it is reading files on the server, not the client.
If you are open to a different SQL client, the one I am maintaining - SQL Workbench/J - can
do precisely what you want:
INSERT INTO flags VALUES ('AD', {$blobfile=/home/flags});
This will read the file from the computer where SQL Workbench is running:
But again: this syntax *only* works with SQL Workbench/J
http://www.sql-workbench.net/blob_example.html
You can also do this directly from within a result of a SELECT statement:

Full disclosure: I am the author of that tool.
