PostgreSQL uses a message-based protocol for communication between frontends and backends (clients and servers). The protocol is supported over TCP/IP and also over Unix-domain sockets.TCP port 5432 is used by the PostgreSQL Database Server, an object-relational database management system (RDBMS) server developed by PostgreSQL Global Development Group.By default, the Postgresql database listens on port 5432. If you want to change this port, you must edit the PGPORT environment variable in /etc/rc. d/init. d/postgresql with the new port number.
What is an example of TCP and UDP : For example, in a video conferencing application, UDP may be used to transmit video data, while TCP is used to transmit control messages and ensure reliable transmission of audio data. Another factor to consider when choosing between TCP and UDP is network conditions.

What protocol is Postgres : Postgres uses a message-based protocol for communication between frontends and backends. The protocol is implemented over TCP/IP and also on Unix sockets.
Default port: 5432, and if this port is already in use it seems that postgresql will use the next port (5433 probably) which is not in use. Postgres uses a message-based protocol for communication between frontends and backends. The protocol is implemented over TCP/IP and also on Unix sockets.
Does Netflix use TCP or UDP
TCP
"Netflix uses TCP because TCP is much time-sensitive and does not require port forwarding. It helps to enable the full bandwidth of the network. We can compress more data at once in TCP and also reloaded data packets do not pose a problem. It also ensures higher video quality and fewer network congestion problems.DNS has always been designed to use both UDP and TCP port 53 from the start 1 , with UDP being the default, and fall back to using TCP when it is unable to communicate on UDP, typically when the packet size is too large to push through in a single UDP packet.By default, the typical ports used by SQL Server and associated database engine services are: TCP 1433, 4022, 135, 1434, UDP 1434. The table below explains these ports in greater detail. Port 5432 Details

How do I enable TCP in Postgres : To enable the PostgreSQL server to accept TCP connections, you must modify two configuration files and then restart the server. You must add the -i option to the /etc/sysconfig/pgsql/postgresql configuration file which is used to start the server. Simply adding the -i option is not enough.

How do I know if Postgres is running on 5432
How to figure out if PostgreSQL database is running
Check if PostgreSQL is listening on port 5432: [11:20]root@onms:~# ss -tulpn | grep 5432 tcp LISTEN 0 128 :::5432 :::* users:(("docker-proxy",pid=26410,fd=4))
Check systemd status.
Check if connection to PostgreSQL database is working.
By default, PostgreSQL uses unencrypted connections. For more secure connections, you can enable Transport Layer Security (TLS) support on the PostgreSQL server and configure your clients to establish encrypted connections.PostgreSQL supports various numeric data types including smallint, integer, bigint, decimal, numeric, real, double precision, serial, bigserial. It has below data types: Integer types – Whole number data types are smallint, integer and bigint.
Is YouTube TCP or UDP : Because the delay is not critical and TCP transfers can be easily handled over HTTP and web browsers without the need for additional plugins and software, video streaming services such as Netflix, Hulu, and Youtube all use TCP to reduce the buffer time and avail other facilities.
