Обсуждение: How to add an userA to login postgresadmin

Hi folks,

RH8.0
postgresql-7.4.3.tar.gz

I have postgresql-7.4.3 installed

$ whereis pgsql
pgsql: /usr/local/pgsql

and have created "postgresadmin" for root
# adduser postgresadmin

root can su postgresadmin without password

Now I expect to add 'userA' to login as postgresadmin
with a password

Can I perform following step to reach my goal;

# adduser userA postgresadmin passwd xxx

Kindly advise.  TIA

B.R
Stephen

stephen,
try adding the user like you normally would.  Did you know the system users and database users are not necessarily the
sameperson?  With that in mind, after adding the user, create an alias in .bashrc like  
alias psql='/usr/local/psql -U postgresadmin -d my_db_name'
Furthermore, in /home/username (that is, that user's ~ home directory) you can put a .pgpass file which contains the
passwordfor postgresadmin 
HOWEVER, it would have been simpler to simply use the 'postgres' system account as it is the universal default

Hi joseph,

Tks for your advice.

I am prepared to allow useA to su 'postgresadmin'.  I
don't want to give userA the 'root password' so that
he can su 'root' and then su 'postgresadmin'

I performed following steps;

# touch /home/satimis/.pgpass
# pico /home/satimis/.pgpass
adding 'abc' as passwd

cat /home/postgresadmin/.bashrc
# .bashrc
# User specific aliases and functions
# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

Whether adding following line after 'fi'
alias psql='/usr/local/psql -U postgresadmin -d
my_db_name'

kindly advise.

Beside what shall I type for 'my_db_name”
