I create a database in pgadmin 4 and I'm trying to import the sql file. It throws an error like schema public is already exists and i'm unable to run the file and create tables with data. Please help me out in this at earliest
This isn't a bug - future questions of this nature should be sent to either the -novice or -general lists.
Manually drop the public schema in your created database before restoring your sql file into it.
