However, if I want to make certain changes to the database, I have to drop the extension and then re-create it (I don't want to update the version number for the initial release). So, what is the normal way of creating some test data to put in the database because obviously, when you do DROP EXTENSION, it deletes everything?

I tried the pg_dump and all I got for the output was this:

there was definitely extra content in the database at the time. Things like users and blog posts etc but none of that seems to have been included in the dump. Having said that I did use JetBrains DataGrip to do the pg_dump so maybe there is a command-line argument I am missing?
