Hi folks,
probably this is a question you've heard so many times
but I wasn't able to find a solution to it.
I'm using a shell script to create a textfile for me.
It looks like
#!/usr/local/bin/bash
psql -c "select foo from bar;" -d database1 -t
psql -c "\q" -d database1
exit 0
The second psql -c "\q" command is used to logout from
the first database. But I'm not sure whether this is
correct. How do I mix these sql and psql meta-commands
otherwise if I want to be able to use myscript >
output.txt to get the output from this select
statement in the file output.txt. I'm planning to
write a cron job for it too.
Another issues is passwords. Normally when I log onto
database1, I have to issue a password because only the
superuser is trusted in the pg_hba.conf file. However
for scripts that I want to be able to run in the
background like this one, I had to add an entry to the
pg_hba.conf file to trust this user also. But as from
security point of view, I'm wondering if this is the
best way to achieve it.
Thanks in advance
