How to Start Stop Postgresql in LiNUX:

Start stop Postgresql in Linux :

Here we are using postgresql of version 15.

systemctl stop postgresql-15
systemctl start postgresql-15

or, with pg_ctl commands also, we can do the same.

pg_ctl start -D /path/to/your/data_directory

Optionally, you can specify a log file:

Syntax :
pg_ctl start -D /path/to/your/data_directory -l /path/to/logfile

Syntax : 
pg_ctl stop -D /path/to/your/data_directory
