I followed one PostgreSQL tutorial step by step. One session to use PSQL to execute sql files to create a new database in PostgreSQL.
copy paste the sql file within "C:\Program Files\PostgreSQL\12" directory.
execute the following code \i C:\\Program Files\\PostgreSQL\\12\\demo-big-en-20170815.sql
Failed The message shows C:: Permission denied then tried \ir "C:\\Program Files\\PostgreSQL\\12\\demo-big-en-20170815.sql" Failed The message shows unrecognized win32 error code: 123"C:/Program Files/PostgreSQL/12/createdatabasesupertest.sql: Invalid argument
SQL file probably was wrong. SO I tried to create a simple sql file (create a new database). Then I follow the above mentioned step to execute the file on windows PSQL. But it failed the same way just like the above mentioned.
So basically my PSQL can not run script files. What should i do?
