cd /software/postgresql-14.0

./configure --prefix=/u01/postgres/v14

cd /u01/postgres/v14/bin >> Verify if contents are showing

cd /u01/postgres/v14

mkdir data

cd data

chown -R postgres:postgres /u01/postgres/v14/data

max_connections = 100 
unix_socket_directories = '/tmp' 
log_destination = 'stderr'
logging_collector = on 
log_directory = 'log'  
log_filename = 'postgresql-%a.log'
