Why is the table not visible through the terminal in postgresql?

Question

PostgreSQL

I create a table through Hibernate and it is created, since I see it with all the fields in the IDE, the idea is, but I can’t find it in the database through the terminal, tell me what I’m doing wrong !?
I also recently moved from Windows to Ubuntu and from mysql to postgresql, if something seems stupid, I apologize, but I can’t catch up.
What I did before created user alexroot and gave him rights to the testproj database Created alexrole group and
added alexroot there gave rights to the database and changes to the database to look through the terminal sudo -u postgresql psql postgres=# \c testproj connect to testproj-# \dt list of tables
Conclusion No relation found - Why?
