Type "help" for help.

tsvt=# \dt+

(1 row)

It should have tables 'trade', 'trade4' and some others.

What about?

\l+ (Letter “el”)

David J.

Well, it gives something:

tsvt=# \l+

tsvt      | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 |                       | 8089 MB | pg_default |
(4 rows)

tsvt is needed database and it has 8089 MB which sounds promising.

Show search_path;

?

David J.

It has:
tsvt=# Show search_path;
   search_path  
-----------------
"$user", public
(1 row)

'user' is literally the name of the current linux user.

How about

\dn

David J. 

OK, the issue is fixed. I just tried to fix myself (by looking at security and user access right doc pages) and screwed the database even more. Then I restored the db from backup and it worked. I have no idea why. In previous cases I was shutting down postgresql normally (via systemctl stop) as just now, why restoring didn't work in previous cases remains a mystery for me. Just for the record, this is output from working db:

tsvt=# Show search_path;
   search_path  
-----------------
"$user", public
(1 row)
