You want to use \i to read a file and execute all the commands in it but you get an invalid argument error
Windows and linux use a different syntax for file locations. The backslash is the main problem. To execute a script, you should double all your backslashes, this can be used to run scripts from an UNC path to.
postgres=# \i y:\server\script.sql
y:: Invalid argument
If you use the following
postgres=# \i 'y:\\server\\script.sql'
Your script will, if the syntax is correct, work.
