How we can connect to specific database by using sql commands in pgadmin4 postgresql
in psql command line,its already working \c database name,same thing we want to connect to specific database in pgadmin4 postgresql
The pgadmin4 SQL window executes only SQL commands, which are bound to a specific database. \c is an internal psql command.
You need to open separate SQL windows per database in pgadmin4.

I'm running PostgreSQL through a Docker container. I entered the container and used psql to connect to postgres. I created two databases then created a table in test_db. I checked pgAdmin4 and the databases were there but the students table is not showing up in the UI. Not sure why if the databases are showing up?
I see you connected to 'test_db' database in pgadmin, but to 'postgres' database in psql. If you want to see 'students' table from 'test_db' database in psql, you need connect to 'test_db' database firstly instead of 'postgres' database. You can use '\c test_db' command for that in psql, or '-d test_db' command-line parameter when launching psql from command line.
I'm trying to execute following Postgres 9.6 commands over JDBC connection
CREATE USER my_db WITH SUPERUSER PASSWORD 'my_db';
CREATE DATABASE my_db;
GRANT ALL PRIVILEGES ON DATABASE my_db TO my_db;
\connect my_db; -- THIS ONE FAILS
SET ROLE my_db;
CREATE SCHEMA my_db AUTHORIZATION my_db;
"\connect" command fails as not recognized. Is there way to connect other database staying within the same JDBC connection?
UPD: "CONNECT TO ..." and "EXEC SQL CONNECT TO ..." also fail.
Backslash commands are not PostgreSQL SQL commands, they're commands in the psql command-line utility. Behind the scenes, \connect just closes the connection and opens a new one.
PostgreSQL its self does not have any way to switch databases on a connection.
Disconnect and reconnect to the other DB.
I am new to postgresql. I've been using the psql tool to get familiar with the sql commands. Why isn't my psql installation recognizing the CONNECT and DISCONNECT commands?
try this instead: \c is an alias of sorts for connect under psql.
\c mydb;
and
\?
will give you some help as well.
there are no CONNECT or DISCONNECT...

How can I move or switch one database to another database using PostgreSQL 9.3 version in shell script(psql)?
Example:
testdb=#
to
mydb=#
If you mean in a script sourced by psql via -f or \i, you can use the command \connect (shorthand \c).
It doesn't just switch databases, it actually disconnects and reconnects. Any SET commands, etc, are not preserved across reconnection.
Simply use below statement:
\c database name
Can someone give the steps to updating my database using psql command line terminal program?
I have created a PostgreSQL database in pgAdmin and I have backed it as PLAIN file (plain-text script). I can't restore that file in pgAdmin. In this this website, it says you can execute a plain-text script file using the "psql command line terminal program", to recreate the database and load data.
So I'm just wondering if someone can give steps to doing this so I can update my current database (outside of pgAdmin).
Run in a shell of your database server as user postgres (or any other user with the necessary privileges):
postgres#db:~$psql
CREATE DATABASE mydb;
\c mydb
\i /path/to/backup.sql
Thereby you create a database, connect to it and run the plain text SQL script from the file to restore the contents.
Details about psql in the manual.
