Re: error on connecting port 5432

Thanks a lot Tom, I appended the -h /tmp and it worked.

I need just one more help from you.

Could you tell me that why & how that socket file existed in /tmp directory.

What is the practice to make sure that this file (.s.PGSQL.5432)
should be inside /var/run directory ? so that it will not throw such
error.

Please help me.

Regards,
Atul
